Astrometry, photometry and morphological classifications are derived from C C D images for all 463 galaxies in Hickson's sample of 100 compact groups. Some minor revisions to the membership of the original catalog are made.  At high galactic  latitude (b > 30°), the catalog is estimated to be 90% complete for groups with total BT magnitude 13.0 or less.  49% of all the catalogued galaxies, and 48%  of first-ranked galaxies are spiral. No significant difference is found between the distribution of morphological types of first-ranked galaxies and all group galaxies. Morphological concordance occurs among galaxies within a group: more galaxies are the same type (spiral or nonspiral), than would be expected by chance. Galaxy morphological type correlates with group optical luminosity and, more strongly, with velocity dispersion, but not with galaxy space density. These results imply that the morphological types of galaxies in compact groups are strongly influenced by the environment, and that this influence occurs mostly at the time of galaxy formation. Fields surrounding 97 compact groups with known redshifts were examined on the Palomar Observatory Sky Survey prints. 3889 galaxies were identified within 1.125h  -1  Mpc of the centre of each group. Coordinates, magnitudes, diameters, and  Hubble types are derived for these galaxies. 78% of the groups show no significant excess of field galaxies within 0 . 5 h  _1  Mpc. This indicates that most compact groups  are truly isolated. 59% of these field galaxies were classified as spiral, a higher fraction that for the group galaxies. This difference is more pronounced for groups which do show a significant field galaxy excess. These results indicate that most  ii  groups are dense dynamical entities. Monte-Carlo calculations indicate that 35% of galaxy quintets are predicted to contain a single discordant redshift due to the chance alignment of an unrelated field galaxy. This is in agreement with the observed number of four discordant quintets in 10. These results are consistent with the cosmological interpretation of galaxy redshifts.  111  Table of Contents ABSTRACT  ii  LIST OF TABLES  vi  LIST OF FIGURES  vii  PREFACE  viii  1.

He was caught in an avalanche while descending Mount Robson, the highest peak in the Canadian Rockies.  Enrico was nearing the completion of his Ph.D. program at the time.  The material presented here summarizes the work in which Enrico was engaged during the course of his studies. This thesis represents my attempt to consolidate the results of his research from material that he had written, conversations we had before his death, and from computer files tha.t he left. Some of this work was done in collaboration with others, including myself. The rest is entirely Enrico's work, including the extensive survey of the environments of compact groups, discussed in Chapter 4. Some of the results presented here have now appeared in print in scientific journals. This thesis presents these and new research results in a uniform manner, to best illustrate the continuity of the work. Any errors or omissions in the text are entirely my responsibility. Enrico made important contributions to science during his all too brief career. He is sorely missed by all those who knew him, and particularly by his family: Anna, Bruno, Cristina, Rita and Sylvia. It is my hope that in this thesis Enrico's work will endure, and perhaps more importantly, will form a sound basis for further research. This would be a fitting tribute for a scientist.

The typical projected separations between the galaxies in a group is comparable to the diameters of the galaxies themselves. Since it is generally believed that such configurations are unlikely to arise by chance, most, if not all, of the galaxies in compact groups are likely to be physically associated. Because of their close proximity, these galaxies are likely to be affected by the gravitational tidal fields of their near neighbours. Indeed, many of these galaxies do show morphological peculiarities indicative of gravitational interaction. It follows that the space density of galaxies in many of these groups is very high, often exceeding that found in the cores of large clusters. Compact groups are the densest known aggregates of galaxies in the Universe. The number of known compact groups is not large. Less than a decade ago  1  only a handful were known, found primarily because of their peculiar appearance on photographs of the sky. Today more than a hundred are known, many of which are described in this thesis. Most of these groups are nearby on an extragalactic scale. The typical group has a redshift of some 6000 km s e c , placing it at a distance of -1  some 60 to 100 Mpc (180 to 300 million light years). B y comparison, the distance to the nearest large galaxy (M31 in Andromeda) is about 0.7 Mpc, and distances to the most distant galaxies known are of order 3000 Mpc. The likely reason that more groups have not been found, is that they are difficult to detect at larger distances. Despite the relatively small numbers of known compact groups, it is believed that they represent a significant fraction of the matter in the universe. Recent estimates suggest that about 1% of the luminous matter in the universe is located in compact groups. This surprising result places a greater importance on the study of these systems. Because of galaxy mergers, described below, the fraction of matter that at one time was located in compact groups may be considerably larger. These groups may play an important role in the evolution of many galaxies. Spectroscopic studies reveal that the relative velocities of galaxies in these systems are generally comparable to galaxy rotation velocities. This makes the galaxies particularly vunerable to gravitational interactions. Unlike the situation in rich clusters, which have typical velocity dispersions of order 1000 km s e c , galaxy -1  encounters in compact groups are slow enough to allow significant disruption of the galaxies. Compact groups are therefore potentially fruitful laboratories for the study of galaxy interactions and their effects.  2  1.2  History  The first compact group of galaxies was discovered late in the last century by M . E . Stephan (1877) at the Observatory of Marseilles. This group, which bears the name "Stephan's Quintet", is perhaps the best known example of a compact group. About seventy years later, a second, even more striking, compact group was discovered by C. K . Seyfert (1948a, 194Sb). Subsequently, several more systems were found in the course of visual surveys of the Palomar Observatory Sky Survey (POSS) plates in search of interacting galaxies (Arp 1966, Vorontsov-Vel'yaminov 1959, Shakhbazyan 1957 and subsequent papers). The discovery of these groups created considerable interest, particularly when spectroscopic observations were obtained. It was found that the galaxies in many groups appear to be moving too fast to be bound to the group by the gravitational attraction of the visible matter. Ambarsumyan (1961) consequently suggested that they may be exploding systems. A n alternate hypothesis (Burbidge and Sargent 1971) holds that they are bound systems, with the necessary gravitational attraction being provided by a large amount of unseen "dark" matter in the groups. The situation became even more complex when it was discovered that many groups contained galaxies whose redshifts were completely different from those of the other group members. If these redshifts are due to the cosmological expansion of the universe, these galaxies could not be at the same distance as the others, but must be aligned with the group by chance. Alternatively, if these galaxies are in fact bona fide group members, a radical new explanation would be required for  3  their redshifts. One suggestion was that these galaxies are being ejected at very high velocities (as much as several percent of the speed of light). The subject of these discordant redshift galaxies remains controversial to the present day. It will be discussed in some detail in Chapter 5. Interest in these groups was recently heightened by the suggestion (Hickson, Richstone, and Turner 1977) that the time scale for gravitational instability is significantly shorter than the Hubble time in many systems. It is therefore expected that galaxies in such groups will merge to form relics, possibly resembling isolated elliptical galaxies, in a time short compared to the age of the Universe. The obvious question arises as to how the groups that we see today have survived until the present time. Equally important is the related question of the number of groups that have been destroyed by galaxy mergers. For every group that we see today, there may be many more that existed in the past. Initial studies suggested that merging would occur rapidly, and that there must be many more relics than visible groups. Williams and Rood (1987) suggested that it might be difficult to reconcile the observations with known physical laws. At the very least, almost all elliptical galaxies would have had to have been formed in compact groups. These apparent difficulties motivated some (Mamon 1986, 1987) to suggest that the groups were much less dense than they appear to be, and are mostly due to fortuitous chance alignments of galaxies in loose groups. However, there is mounting evidence (reviewed by Hickson and Rood 1988) that most groups in this catalog are in fact true dynamical systems, with only a few galaxies being due to chance projections.  4  1.3  T h e Present Sample  Because compact groups contain few galaxies, typically only four or five, it is difficult or impossible to draw quantitative conclusions from the study of individual systems. We can measure only angular positions in the sky, so do not know the three-dimensional spatial locations of galaxies. Also, spectroscopy provides only one component of velocity, that along the line of sight, so we are largely ignorant of the true velocities of the galaxies. Progress can be made, however, by assuming that galaxies are randomly located in groups, and that velocities are randomly oriented. In this way, statistical averages could be performed over a large sample of groups, provided that this sample is selected in a uniform and unbiased manner. In this way average properties of compact groups may be determined. In an attempt to define a large, statistically homogeneous sample of compact groups, Hickson (1'982) conducted a visual search of the entire set of 935 POSS red prints to identify compact groups using well defined selection criteria. The criteria he used were the following:  1. (magnitude concordance) There must be at least four galaxies whose apparent red magnitudes differ by no more than three magnitudes. The smallest circle containing the centres of these galaxies defines the centre of the group, and its radius RH2. (isolation) There must be no other galaxies with magnitudes within this range or brighter, closer than 3RH from the centre of the group.  5  3. (compactness) The mean surface brightness of the group, defined as the total red magnitude of all member galaxies (as identified in 1) distributed uniformly over a circle of radius RH, must be at least as bright as 26.0 mag arcsec . -1  Hickson found exactly 100 groups which satisfied all three selection criteria. The clearly defined selection criteria of this sample make it useful for statistical investigations of the nature and properties of compact groups. In order to exploit this potential, subsequent observational programs have provided photometry, spectroscopy, and radio maps of most, if not all, galaxies in the groups. From high-resolution C C D images in two colors of Hickson's entire sample of group, and the resulting photometric data, (discussed in Chapter 2) two galaxies were found that were misidentified stars and 11 new galaxies were found to satisfy the original criteria using photometric magnitudes. We have therefore revised Hickson's catalog slightly, removing the misidentified objects and including the new galaxies. In this thesis we present these revisions, and new data for the entire catalog. Following this is a discussion of the completeness, and other aspects of the catalog. We then consider the morphology of galaxies in compact groups, and from this draw conclusions concerning the evolution of the groups. Finally, we examine the controversial question of discordant redshifts in compact groups, using the best available data.  6  Chapter 2 P H O T O M E T R Y  2.1  Introduction  The sample of compact groups identified by Hickson (1982) was based on galaxy magnitudes estimated visually from the POSS prints. Since magnitudes are needed both for the selection of groups and for subsequent analysis, it is important that accurate magnitudes be determined. We have derived photometric magnitudes from a complete series of high-resolution C C D images obtained with the Canada-FranceHawaii Telescope ( C F H T ) . These images reveal two galaxies that were misidentified in Hickson's catalog, and 11 new galaxies that satisfy the original criteria when photometric magnitudes are used. We have therefore revised the catalog, removing the misidentified objects and including the new galaxies. A n equally important aspect of the groups is the morphology of the individual galaxies. Different morphological types result from fundamental differences in galaxy structure and composition. Elliptical galaxies are generally amorphous collections of  7  some 10  12  old stars, with very little gas. On the other hand, spiral galaxies contain  ordered rotating disks of gas and young stars. These galaxies tend to be found in different environments: elliptical galaxies are found mostly near the centres of large clusters; spiral galaxies are common in less dense environments. On the other hand, galaxy mergers may produce systems resembling elliptical galaxies. The fraction of spiral galaxies in a group is therefore an important parameter dependent on both the "initial conditions" present at the time the galaxies formed, and on the subsequent evolution of the group. Morphological type classifications have been made for compact groups (Hickson 1982, Williams and Rood 1987), based on the POSS images. Because many galaxies are small and poorly resolved, and because the dynamic range of the POSS prints is often insufficient to reveal delicate structures in these faint galaxies, these type classifications are not totally reliable. The C C D images, however, have higher resolution and greater dynamic range. From these it is possible to make more accurate galaxy type classifications. In this chapter, we present the photometric and morphological data for the revised catalog of compact groups. We use these data to examine the completeness of the catalog and describe some basic statistical properties of this sample. The morphology of the groups is the subject of Chapter 3.  8  2.2  Observations and D a t a R e d u c t i o n  a) Galaxy Positions Hickson measured coordinates for the optical centres of all galaxies in his catalog on the POSS using the Mann measuring engine at the V L A . The measurement error is estimated to be approximately 2 arcsec R M S . However, uncertainties in locating the centre of a bright galaxy can be as much as 5% of the galaxy diameter. These coordinates are listed in Table 6. Positions of the eleven new galaxies in the revised catalog presented here were measured with an x-y microscope on the POSS prints at U B C . Coordinates for these galaxies were determined from their offsets with respect to the other galaxies in the same group with coordinates measured on the V L A Mann engine. We expect the accuracy of these new coordinates (also listed in Table 6) to be comparable to those measured at with the Mann engine.  b) CCD Photometry In a series of three observing runs from 1983 to 1985, Hickson obtained twocolour images of all galaxies in his catalog using the Canada-France-Hawaii telescope. The analysis and interpretation of these images constitutes a large portion of this thesis. The detector used for these observations was a 512 x 320 pixel blue sensitive R C A C C D (Walker et al. 1984), mounted at prime focus on the Wide Field Corrector and the F O C A S l imager/spectrometer (Hickson 1986). The image scale was 0.42 arcsec p i x e l  -1  and stellar images have full-widths at half-maximum ( F W H M )  9  of typically 1.2 arcsec. A l l fields were observed for 200 seconds in both B and R bandpasses. The images were subsequently preprocessed on the U B C Astronomy V A X / I S system using Hickson's ' S T A R ' and C. Pritchet's 'R2D2' (with modifica2  tions by G . Grieve and Kindl) image processing software. Cosmic ray spikes and streaks from saturated star images were removed by interpolating across the short axis of the affected region using a Fourier technique (Hickson and Yedlin 1986). Foreground stars were removed by truncating the intensity to the local background within a circular aperture containing the star. The radius of the aperture was determined by inspection. The intensities in the aperture were then fitted to the background using a numerical relaxation technique. Sky subtraction was straightforward in the majority of cases in which the galaxies fit well inside the C C D field and there was no scattered light from bright stars. In these cases a constant was subtracted based on intensity levels obtained by inspection far from any source. This technique was fast and could be reproduced to within 3%. If the sky background was contaminated by scattered light a tilted plane was fit using a least-squares algorithm with iterative outlier rejection. This method had comparable accuracy. In a few cases a galaxy filled the entire C C D field and it was not possible to obtain a reliable sky value from a single frame. However, in these cases several frames were available of other group members, taken within twenty minutes of time. The sky levels obtained from these agreed to within 5% . The mean of these frames was adopted and used for the problematic frame. Finally, each frame was filtered using a Gaussian kernel with the same F W H M as the seeing profile to reduce pixel to pixel noise and thereby improve the smoothness of the isophotes.  10  Isophotal photometry was done using ' A O L P ' , an image processing package written by R. Scharein at U . B . C . This package performs photometry over a selected range of arbitrarily shaped isophotes very quickly. This makes it particularly suitable for the large sample of irregularly shaped galaxies studied here. It has one inherent difficulty in that a noisy isophote boundary tends to bias the photometry toward lower measured intensities. The extent of this effect was tested using artificial de Vaucouleur's profiles (logI(r) oc r / ) . Since the background in our data - 1  4  is dominated by readout noise, varying amounts of additive Gaussian noise were added to each test frame. For typical compact group data the signal to noise ratio after spatial filtering was about 30 to 100. This yields a value of less than 0.01 magnitudes for the bias. Many of the galaxies had overlapping outer isophotes. These were treated using one of two methods. Forty galaxies were members of overlapping pairs. For these, three measurements were made by first slicing the combined image into three sections at the two galaxy nuclei perpendicular to the line joining the nuclei. The total intensity in the slice containing the overlap was then divided between the two galaxies in proportion to the brightness measured in each of the two other slices. This is a reasonable technique if the galaxy images have retained their bilateral symmetry, despite their overlap. The above technique could not be used for 159 galaxies which were members of multiple overlapping systems or were in pairs with insufficient symmetry. For these, intensities within the outer isophotes were divided among the individual galaxies in proportion to their brightness within the inner non-overlapping isophotes. This technique tends to assign brighter magnitudes and larger sizes to high central sur-  11  face brightness galaxies. The question then arises as to how one should define the boundary of a galaxy when it is merging with several others.  The method used  here is felt to be appropriate since it is reproducible and does not attempt to assign arbitrary boundaries to the galaxies. The procedure yielded isophotal magnitudes to a standard surface brightness of HB — 24.5 mag arcsec in the B band and fiR = 24.0 mag arcsec -2  -2  in the R band.  These limits are due to background noise and the small size of the C C D field which prevented reaching fainter isophotes of some large galaxies. Total asymptotic BT magnitudes were derived for the galaxies by fitting the observed intensity profiles to the standard profiles published in the Second Reference Catalog of Bright Galaxies (de Vaucouleurs' et al. 1976, RC2). The published profiles were found to agree well with a family of quartic polynomials parametrized according to morphological type. The appropriate polynomial was then matched to the observed profile and the corresponding correction to the galaxy's magnitude was thus obtained. Corrections for internal and external extinction were also included as described in the RC2. No K-corrections were included. Whenever possible, errors were estimated for the BT magnitudes by comparing our magnitudes with other published BT magnitudes, de Vaucouleurs and coworkers (RC2, de Vaucouleurs and Bollinger 1977, de Vaucouleurs, Corwin and Bollinger 1977, Olson and de Vaucouleurs 1981) have published values of BT for 22 galaxies in this catalog (16abcd, 22a, 44abcd, 68abc, 90abcd, 91a, 92abcde). We have adopted the de Vaucouleurs BT magnitudes for these galaxies in Table 7.  12  c) Morphological Types The morphological types were determined by visual inspection of the C C D images using the classification system in The Hubble Atlas of Galaxies (Sandage 1961). Elliptical galaxies were assigned an ellipticity from the axial ratio of the fiB — 25.0 mag arcsec  -2  isophote. Disk galaxies were assigned a type — 0, 0a, a,  ab, b, be, c, dc, d, dm, m — according to bulge to disk ratio and arm spacing by comparison with examples in the Hubble Atlas. Compact, c i , and Magellanic, Im, irregular galaxies were identified morphologically or, as a last resort, by their low B — R color. Numerical codes were also assigned to each morphological type as listed in Table 1. The equivalent code from the RC2 is also included for comparison.  2.3  Discussion  a) Completeness The completeness of the catalog as a function of magnitude was investigated by considering the cumulative distribution of groups over total group magnitude m, obtained from the uncorrected Bx magnitudes of the members of the group. As Figure 1 shows, the observed distribution is approximately linear, having a slope of 0.6 for m < 13.3, but becomes nonlinear at larger magnitudes as would be expected from incomplete sampling. The curve fitting the data points in Figure 1 has the equation 2N N(m) =  arctan(dex(0.6(m  — rn )))  where N = 100 (the number of groups in the catalog) and m  13  (1)  0  0  = 13.75.

In order to investigate the effects of galactic absorption we examined the surface density o of groups (number of groups per square degree) as a function of galactic latitude b. Galactic absorption will increase the blue magnitude of the groups by an amount which we approximated by  = 0.2 csc\b\ (Sandage 1973).  This results in a smaller volume of space being sampled at a given limiting magnitude. If the space density of compact groups is uniform, we therefore expect a relation of the form log a = 0.12 csc\b\ + const. The line with slope 0.12 that best fits the surface density of groups with 1b\ > 30 deg has the equation log a - -0.12 csc\b\ - 2 . 1 2 and is plotted in Figure 2. Points with b < 30 deg fall below this line, indicating that galactic extinction alone is not sufficient to explain the incompleteness. It is likely that confusion caused by galactic stars resulted in fewer groups being found at these low latitudes. The ordinate of this line at csc\b\ = 1 gives a surface density, corrected to the galactic pole, of log o~ = —2.24 corresponding to about one group 0  per 174 square degrees.  b) Multiplicity The revised catalog consists of 100 groups containing a total of 463 galaxies. The distribution of group population is listed in Table 2, for the entire catalog, and  15  CD  UD  CN  CD  ID  CD  ID  CD  CN  —  —  CD  CD  (UJ)M  601  Figure 1: Number of groups vs. magnitude.

There is a strong decline in the number of groups as a function of increasing galaxy population (the multiplicity function). In the full catalog there are less than half as many quintets as quartets, and still fewer groups with more than 5 members. In the bright subset, there are relatively more quintets, but only three groups with more than five members. Can this strong decline in the multiplicity function be a result of the selection criteria? For a given mean surface brightness, a quintet would typically cover 25% more area of sky than a quartet. The area of the vacant ring required by the selection criteria (Section 1.3) is also correspondingly larger, making it more difficult to find an isolated system. The probability of a specified ring of area A being vacant is given by P = r  exp(—aA ), r  where a is the surface density of field galaxies with magnitude in the same range as the group members. The surface density of galaxies in the neighbourhood of the groups is discussed in Chapter 4. The product oA  T  averages about 0.3 for the  quartets studied. A quintet is therefore only slightly less likely to pass the isolation criterion than is a quartet, the ratio of probabilities being P5/P4 ~ 0.93. It appears that the rapid decline in the multiplicity function is largely real. A similar decline, though less steep, occurs in the C F A group catalog (Geller and Huchra, 1983), and Turner-Gott groups (Gott and Turner 1977).  18  TABLE 2 Distribution of Group Population Population  Number of Groups all B < 13.3 T  4 5 6 7 8  60 25 8 6 1  19  18 12 1 1 1  Chapter 3 G A L A X Y  3.1  M O R P H O L O G Y  Introduction  Several results concerning the morphology of galaxies in compact groups were reported by Hickson (1982) and Hickson et. al. (1984). These included the unexpected result that the spiral fraction of first-ranked galaxies is no different from that of all galaxies in the sample. Also, a correlation was found between spiral fraction and group mean surface brightness, in the sense that higher surface brightness groups contain fewer spirals. As very few redshifts were available it was not possible to determine which physical parameter, group luminosity or galaxy space density, or both, was responsible for this effect. These early results, however, were based on rather uncertain galaxy morphological types estimated by visual inspection of the POSS prints. Likewise, the surface brightness was determined from magnitudes estimated visually from these prints. While the morphological types largely agreed with more accurate types determined  20  by Williams and Rood (1987) from second-edition sky survey prints, it is important to reexamine these effects with better data. It is well known, for example, that the morphology of cluster galaxies correlates with cluster type (Oemler 1974) and galaxy location. Dressier (1980a) has found a strong correlation between spiral fraction and local space density. A similar relation is found for galaxies in loose groups (Postman and Geller 1984). It is of interest to determine if the same relation holds for galaxies in compact groups.  3.2  Observational Data  Morphological types for all galaxies were determined by inspection of Hickson's B and R band C C D images. These images were of sufficient quality, often with subarcsec resolution, to allow unambiguous type classifications on the Hubble (Sandage 1961) system. These classifications, and the photometric data of Chapter 2, were combined with spectroscopic data obtained by Hickson and Huchra (1990). These consist of velocities of over 300 galaxies from spectra obtained over a period of several years with the Whipple Observatory 1.5m telescope using the "Z-machine", a photoncounting Reticon system (Latham 1982), by a cross-correlation technique (Tonry and Davis 1979). The estimated errors for these velocities is quite low, typically of order 30 km s . -1  Using these velocities discordant galaxies whose velocities differed by more than 1000 km s  - 1  from the group median were identified and rejected from the  21  sample. The resulting subsample consists of 98 groups of three or more galaxies. Of these, 96 groups have measured velocities for at least one galaxy and 79 groups have measured (and accordant) velocities for at least two galaxies, and 71 groups have measured velocities for three or more galaxies. Data for this subsample appear in Table 3. The columns are as follows: (1) group identification number (Hickson 1982); (2) number of galaxies (not including galaxies with measured discordant velocities); (3) number of spiral galaxies (galaxies of type Sa or later); (4) spiral fraction (ratio of the previous two columns); (5) mean redshift; (6) radial velocity dispersion (from three or more galaxies); (7) blue luminosity (including K corrections from Pence (1976)); (8) galaxy space density. A flat (fi = 1) Friedman model with Hubble constant H = 100 km s Q  - 1  was  used for angular size and flux conversions. Galaxy space density was estimated from the formula n = 3N/AirR where N 3  is the number of galaxies in the group and R is the median projected (2-dimensional) galaxy separation. This estimator is both simple and robust. To evaluate its relation to other estimators we performed Monte-Carlo simulations. From 10000 runs in which four galaxies were placed at random uniformly within a sphere of unit radius the mean value of R was found to be 0.82. Thus n overestimates the density of a homogeneous sphere of four galaxies by a factor 1.81. Rather than apply a modeldependent correction, we chose to use the formula as it stands. Our density estimates should nevertheless be within a factor 2 of, say, Dressier's (1980b) cluster density estimator based on distances to the ten nearest neighbours.  22  TABLE 3 Compact Group Data No.  Ngal  N  sp  fsp  z  log <T (km s" )  log L (W)  1.93 1.74 2.40 2.81 2.75 ... 1.95 2.65  2.56 2.09 2.43 1.52 1.70 2.44 2.05 1.64 1.95 1.89 1.74 2.39  38.11 37.73 37.60 38.25 38.13 38.07 38.07 38.64 38.57 38.20 37.21 38.22 38.28 37.64 38.36 38.10 38.05 37.02 37.47 38.13 38.20 37.41 37.68 37.93 38.20 38.06  1.88 ... 1.86 1.75 2.32 2.19  38.00 37.91 37.89 37.70 38.33 37.63  V  1  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33  4 4 3 5 4 4 4 4 4 4 3 5 5 4 6 4 5 3 4 6 4 3 5 5 7 7 6 4 4 4 4 4 4  2 4 2 3 2 2 3 0 2 3 2 1 1 3 3 4 0 3 3 0 2 2 4 1 4 4 3 2 1 3 4 0 1  0.50 1.00 0.67 0.60 0.50 0.50 0.75 0.00 0.50 0.75 0.67 0.20 0.20 0.75 0.50 1.00 0.00 1.00 0.75 0.00 0.50 0.67 0.80 0.20 0.57 0.57 0.50 0.50 0.25 0.75 1.00 0.00 0.25  0.0339 0.0144 0.0255 0.0269 0.0400 0.0389 0.0141 0.0545 0.0672 0.0161 0.0245 0.0489 0.0416 0.0198 0.0232 0.0132 0.0604 0.0137 0.0142 0.0486 0.0251 0.0090 0.0164 0.0307 0.0211 0.0317 ... 0.0379 0.0445 0.0154 0.0137 0.0408 0.0260  23  2.32 ... 2.36 ... •••  B  log n (Mpc~ ) 3  3.91 3.69 3.19 3.98 4.70 4.75 4.00 4.60 3.73 3.08 3.06 3.75 4.05 3.76 3.48 4.03 5.02 6.73 4.83 4.57 2.01 4.58 3.75 4.65 4.07 4.72 ... 5.00 5.36 3.85 6.35 3.62 4.81  T A B L E 3 - Continued  No.  Ngal  N  sp  fsp  z  log a (km s" )  log L (W)  2.50 2.54 2.41 1.11 2.30 2.17 2.33 2.35 2.11 2.74 2.51 1.63 2.48 ... ... 2.67  37.81 38.61 38.20 37.90 38.11 38.21 38.00 38.17 37.37 38.31 37.54 37.89 37.00 37.57 ... 38.65 38.16 38.02 36.18 38.20 38.07 38.84 38.41 37.54 38.52 37.71 37.73 38.14 38.10 38.96 38.40  v  1  34 35 37 38 39 40 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66  4 6 5 4 4 5 4 6 4 4 4 4 3 4 5 7 4 4 4 4 5 8 5 5 4 3 4 4 4 5 4  2 1 2 4 2 3 0 4 3 2 0 3 1 3 0 3 4 3 4 0 1 4 3 4 1 1 0 4 2 0 0  0.50 0.17 0.40 1.00 0.50 0.60 0.00 0.67 0.75 0.50 0.00 0.75 0.33 0.75 0.00 0.43 1.00 0.75 1.00 0.00 0.20 0.50 0.60 0.80 0.25 0.33 0.00 1.00 0.50 0.00 0.00  0.0307 0.0542 0.0229 0.0292 0.0701 0.0223 0.0133 0.0330 0.0046 0.0722 0.0270 0.0318 0.0094 0.0332 ... 0.0262 0.0433 0.0209 0.0047 0.0527 0.0272 0.0305 0.0207 0.0135 0.0634 0.0130 0.0138 0.0243 0.0356 0.0477 0.0690  24  0.98 2.32 2.20 2.41 2.21 1.96 ... 1.96 2.52 3.46 1.95 2.45 ...

The distribution of galaxy morphological types is shown in Figure 3. The darkly shaded bars indicate the distribution for all galaxies, and the lightly shaded bars indicate the distribution for first-ranked galaxies only. There is no significant difference between the two distributions. The Kolmogorov-Smirnov two-sample test gives a 15% probability that both distributions arise from the same parent. This is also consistent with the spiral-fraction statistics. The spiral fraction of all galaxies in the sample is found to be 0.49, whereas for first-ranked galaxies it is almost identical at 0.48. This agrees with Hickson's 1982 observation that the  26  i — i — i — i — i — i — i — i — i — i — i — i — i  _i  i i l  1  i i_  J  CO  OJ  CD  CD  UOI 4.TJ I n d o j  JO  i  i i  i  i  i  i I l  i  r  l i_  CD U0||3DJJ  Figure 3: Distribution of galaxy morphological types in compact groups. Dark shading indicates all galaxies; light shading indicates first-ranked galaxies only. There is no significant difference between the two distributions.  27  morphology of the first-ranked galaxy does not differ significantly from that of the general population. If significant merging had occurred in the groups we would expect the first-ranked galaxies (the merger products) to be less often spiral. We conclude that significant merging has not occurred in these groups. A comparison of the spiral fraction of group galaxies compared to field galaxies is problematic. Our groups were selected from the red Palomar prints. Estimates of the field galaxy spiral fraction are based on surveys of the blue prints. Since E and SO galaxies are typically 0.5 magnitudes redder than spirals, we should find more of them on the red prints than on the blue prints. For example, from the U G C catalog (Nilson 1973), Gisler (1980) has estimated the spiral fraction of field galaxies to be 0.81. We can estimate what this fraction would have been had the U G C been based on a search in the red. The galaxy log number-magnitude relation (Tyson and Jarvis, 1979) has a slope of 0.6 in the magnitude range of interest. Thus a colour difference of 0.5 magnitudes corresponds to an increase of about a factor of 2 in the relative numbers of early type galaxies. This lowers the spiral fraction from 0.81 to 0.62, compared to 0.49 for the compact group galaxies. Thus it appears that compact groups have a lower spiral fraction than the field, but considering the uncertainties in the above calculation this conclusion is by no means certain. When we consider the morphology of members of individual groups, a significant correlation emerges. Galaxies in the same group have a tendency to be of the same general type (ie. early or late). This effect can clearly be seen from Figure 4 where we plot the number of quartets with 2, 3, or 4 galaxies of concordant type, and similarly for quintets. We define galaxies to have concordant type if they are all early type or all late type. We observe 20 quartets in which all galaxies have con-  28  cordant type. Since about half the galaxies in the groups are spiral, the probability of randomly picking four concordant galaxies is 1/8. The binomial distribution then gives the probability of obtaining 20 concordant quartets in 58 tries as 1.0 x 10~ . A 5  similar effect is seen in the quintets but the significance is less (0.026 chance probability) due to the smaller number of groups. Sulentic (1987) has also remarked upon concordance in these groups of morphological types estimated by Hickson from the POSS. In order to investigate what environmental factors may affect morphological type, we look for correlations between spiral fraction and physical parameters of the groups. Figure 5 shows a plot of spiral fraction vs. galaxy space density in each group. In these and the figures following, bars indicate the standard error for each point. Contrary to results found by others for loose groups and rich clusters we find no strong correlation between spiral fraction and galaxy space density in compact groups. A weak correlation possibly exists at the 2.4% level. This somewhat surprising result is not at variance with Hickson's (1982) correlation of spiral fraction vs. surface brightness, as the latter involves group luminosity as well as density. Figure 6 shows spiral fraction plotted against total blue luminosity of each group. A strong correlation (Spearman r probability = 1.1 x 1 0 ) is found: higher luminosity -4  groups contain fewer spirals. This result is not entirely surprising. Higher-luminosity groups contain higherluminosity galaxies. It has been known for some time that Hubble type correlates with spheroid luminosity (Dressier 1980b, Strom 1980, Meisels and Ostriker, 1984); perhaps the effect seen in these groups is a consequence of this correlation. Figure 7 shows spiral fraction as a function of galaxy luminosity. The solid line shows  29  Figure 4: Galaxy morphology concordance. Darkly shaded bars show the number of groups of N galaxies containing 2, 3, 4, or 5 concordant (early or late) morphological types. Lightly shaded bars show the number expected for a random sample of N galaxies selected without regard to group membership. The large number of groups with all galaxies concordant is highly significant. 30  /  -A  to  c OJ  Q in i_ QJ  xt-  q  CO  CD  CO  LO  CD  CD  u o j i D T j j j  CM CD  CD  irjjjds  Figure 5: Spiral fraction vs. estimated galaxy space density.

The shapes of the two distributions are similar but, if we exclude the very brightest galaxies, there is a clear difference. For a given galaxy luminosity, the spiral fraction is lower in compact groups. The significance of this difference can be shown in a simple and non-parametric way: Under the null hypothesis that for a given luminosity, there is no significant difference between the spiral fractions of group and field galaxies, the points in Figure 7 would be equally likely to fall above or below the line. The probability of 10 or more of 11 independent points falling below the line is given by the binomial distribution  If galaxies brighter than 3 x l 0 H ^ are excluded, the probability drops to 0.001. Since 3 7  environment is the only obvious difference between the two samples we conclude that the lower spiral fraction in compact groups results somehow from their higher density environment. A further correlation appears when spiral fraction is plotted against group velocity dispersion (Figure 8.).  Groups with higher velocity dispersion contain a  higher fraction of early-type galaxies. The chance probability of obtaining the observed Spearman rank correlation coefficient is 1.3 x 1 0 . The upturn for the highest - 7  velocity dispersion groups in the figure may indicate some contamination of these groups by unrelated field galaxies. This correlation runs counter to what might be expected if galaxy collisions and mergers are destroying spirals in the groups.

This implies that galaxy morphological types have not been significantly altered by dynamical evolution in these groups. This conclusion is also supported by the normalcy of the first-ranked galaxies. We must conclude that the morphology of galaxies in compact groups is influenced mainly by environmental factors at the time of galaxy formation.  3.4  Discussion  A natural question is whether the observed correlation between spiral fraction and velocity dispersion might simply be the result of the type-luminosity relation for individual galaxies (Figure 7) and a possible luminosity-velocity dispersion correlation for the groups. Such a correlation could arise if the groups are in virial equilibrium with a small dispersion in size, since, from the virial theorem L ~ M ~  V R. 2  This question can be investigated by means of the Spearman partial rank correlation coefficients (eg. Macklin, 1982). The partial correlation coefficient for spiral fraction with velocity dispersion is 0.560. For spiral fraction with luminosity it is 0.169. The significance levels associated with these two correlations are 2.4 x 1 0  - 7  and 0.16 respectively. This shows clearly that spiral fraction is dependent on velocity dispersion. It also shows that there is no evidence for an independent correlation between spiral fraction and luminosity. The spiral fraction - velocity dispersion correlation is the fundamental one. We have presented what we believe to be strong observational evidence that  36  galaxy morphological type is correlated with galaxy environment in compact groups. Specifically, we find a morphological type concordance and a strong morphology velocity dispersion correlation. We have argued that these correlations must be be a result of environmental influences on galaxy structure and composition at the time of galaxy formation, and not due to subsequent dynamical evolution as we know it. The principal reasons for this conclusion are the nature of the type-velocity dispersion correlation, and the lack of morphological abnormality in the first-ranked galaxies. These correlations provide further support for the view that most groups in this catalog are true physical systems of high space density and are not transient dynamical or geometrical configurations (Mamon, 1986). It seems unlikely that chance configurations of otherwise unrelated galaxies would show morphological concordance or a strong correlation of galaxy morphology with velocity dispersion. Also, if the groups are transient alignments in low-density systems, denser host groups would produce alignments of higher apparent density. We should then see the morphology-density relation observed in loose groups. As we have shown, this correlation is absent, or at best very weak, in our data.  37  Chapter 4 G R O U P  4.1  E N V I R O N M E N T S  Introduction  The environment of compact groups contains clues to their nature and origin. By studying the environment, we can determine whether these groups are truly isolated entities, or are subunits of larger clusters. If these groups are chance alignments in loose groups, we should see a significant clustering of galaxies around them. Studies of the environment are essential to address the question of discordant redshifts. In order to estimate the number of field galaxies expected to be aligned with a group, by chance alone, we need to know the surface density of field galaxies in the vicinity of the group. As the galaxies in and around compact groups are generally too faint to be included in published catalogues, in order to investigate the group environments, it was decided to examine the POSS prints directly.  38  Searches of the areas around these compact groups have been made independently by two groups. Sulentic (1987) counted field galaxies w i t h i n circles of radii 0.5° and 1° centred on the groups. W i l l i a m s and R o o d (1989) examined field galaxies w i t h circles of radii 10 RH- In the present study galaxies were examined i n a circular region of fixed metric diameter, corresponding to 3.0 M p c for a H u b b l e constant of 75 k m s e c  - 1  M p c . It was possible to do this because redshifts had recently been - 1  obtained for 98 of the 100 groups (Hickson and Huchra, private communication).  4.2  Observations  T h e P O S S red prints containing 97 compact groups w i t h known redshifts groups were searched for galaxies w i t h i n a circle of diameter corresponding to 2 . 2 5 / i centered on each group (h is the H u b b l e constant i n units of 100 k m s  - 1  -1  Mpc  Mpc ). - 1  T h i s radius is large enough to provide a representative sampling of the local field population, and small enough that it can be uniformly applied to a l l groups. N o redshift was available for two groups (27 and 50). A n o t h e r group (54) was not searched because its very low redshift and wide magnitude range made this impractical. E a c h region was scanned w i t h a binocular microscope at 32 x magnification and the positions of a l l objects resembling galaxies were noted on an overlaid transparancy. These objects were selected to be not brighter than, and not more than three magnitudes fainter than, the brightest group galaxy. T h i s is consistent w i t h Hickson's (1982) criteria for membership i n his catalogue. A glass plate replica of a millimetre grid was placed over each sky survey print and the positions, sizes, magnitudes and morphological types were estimated for a l l the galaxies noted. Posi-  39  tions were measured to within ±0.1 mm. Major and minor axis sizes for the galaxies were measured using a rotatable reticle mounted in the microscope eyepiece. These were measured to within ±0.1 mm. Magnitudes were estimated by interpolating between the magnitudes of the original group members as estimated by Hickson (private communication). The resulting magnitudes are expected to be accurate within ±0.5 typically.  4.3  Results  In order to assess the degree of central concentration of field galaxies near the groups, we have divided the counts in inner (R < 0.5k- Mpc) and outer (0.5k- < R < 1  1  1.125ft Mpc) regions. (R is the distance between the field galaxy and the centroid -1  of the group.) A central concentration would appear as higher surface density of field galaxies in the inner region than in the outer region. The complete list of data resulting from the survey of group environments is presented in Appendix B . We list there, in Table 8, coordinates, diameters, estimated magnitudes, and Hubble type classifications for all galaxies found in the environments of these groups. In the present section the results obtained from these data are summarized. Mean properties for galaxies surrounding each group are listed in Table 5. The column headings for this table are as follows: Column 1: Group catalog number. Column 2: Radius of search area  40  Column 3: Number of catalogued group galaxies Column 4: Number of catalogued field galaxies Column 5: Number of spiral field galaxies Column 6: Number of field galaxies in inner region Column 7: Number of field galaxies in outer region Column 8: Mean galaxy surface density in inner region Column 9: Mean galaxy surface density in outer region column 10: Mean spiral fraction of group galaxies (including those with discordant redshifts) column 11: Mean spiral fraction of field galaxies  Consider first the question of possible field galaxy concentration towards the groups.  From the counts in the outer region, we can predict the counts in the  inner region that would result from a uniform distribution (no concentration) of field galaxies, by multiplying by the ratio of areas, 0.2462. B y comparing this to the number of galaxies actually observed in the inner region we can test the null hypothesis (that there is no central concentration). Applying this test we find a significant central concentration of field galaxies, at the 3<J level in 21 groups (groups 1, 12, 30, 31, 35, 36, 37, 48, 49, 60, 62, 64, 65, 67, 68, 69, 70, 71, 79, 84, and 86). Thus only about 22% of compact groups are located in a significant density enhancement of field galaxies. We conclude that the majority (of order 3/4) of compact groups are truly isolated. Now consider the morphology of these galaxies. The mean spiral fraction of these 97 compact groups is 0.504. The mean spiral fraction for the field galaxies is  41  0.589. Thus the spiral fraction is lower i n the compact groups than i n the field, as suggested by Hickson (1982), but only marginally lower. Now suppose that compact groups were due to chance alignments i n loose groups as claimed by M a m o n (1987). T h e n we would expect the spiral fraction of compact groups to be the same as that of the field, at least i n the 21 groups which show a significant enhancement of field galaxies nearby. In fact, the reverse is true. For these groups the mean spiral fraction is 0.436 compared to 0.636 for the surrounding field galaxies. T h e fact that most groups are isolated, and the lower spiral fraction i n those groups that are not strongly suggests that the large majority of groups are not chance alignments.  42  TABLE 5 Compact Group Environments Group  R  N  F  F  NFI  N  FS  arcmin 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33  37.7 88.6 50.8 50.8 31.5 33.0 89.9 23.4 19.2 80.5 70.3 26.7 30.9 65.5 55.2 95.5 21.2 94.3 90.6 26.4 50.8 143.4 94.1 42.0 60.5 40.8 23.5 29.0 84.1 94.3 31.5 49.6  4 4 4 5 4 4 4 4 4 4 4 5 5 4 6 4 5 4 4 6 5 5 5 5 7 7 6 4 4 4 4 4 4  NFO  o-i  arcmin  -2  arcmin  19 27 23 12 44 20 35 17 5 25 46 13 15 43 28 15 23 106 85 22 5 24 45 19 30 20  13 18 18 6 9 11 15 8 5 13 24 8 6 26 13 12 9 62 39 15 2 13 32 13 24 9  9 0 4 0 0 4 7 3 2 1 14 6 3 12 6 4 9 31 20 6 0 8 11 6 4 8  10 27 19 12 44 16 28 14 3 24 32 7 12 31 22 11 14 75 65 16 5 16 34 13 26 12  0.01018 0.00000 0.00249 0.00000 0.00000 0.00590 0.00139 0.00882 0.00879 0.00025 0.00456 0.01361 0.00506 0.00450 0.00317 0.00071 0.03237 0.00562 0.00393 0.01384 0.00000 0.00063 0.00200 0.00548 0.00176 0.00776  0.00278 0.00136 0.00291 0.00184 0.01762 0.00581 0.00137 0.01014 0.00324 0.00147 0.00257 0.00391 0.00498 0.00286 0.00286 0.00048 0.01239 0.00335 0.00314 0.00908 0.00077 0.00031 0.00152 0.00292 0.00282 0.00286  16 168 35 196 9 8  7 50 26 104 7 4  6 28 18 54 3 2  10 140 17 142 6 6  0.01748 0.05362 0.00410 0.00978 0.00488 0.00131  0.00717 0.06600 0.00095 0.00633 0.00240 0.00097  43  fsG  fsF  0.50 1.00 0.50 0.60 0.50 0.50 0.75 0.00 0.50 0.75 0.75 0.20 0.20 0.75 0.50 1.00 0.00 0.75 0.75 0.00 0.40 0.40 0.80 0.20 0.57 0.57 0.50 0.50 0.25 0.75 1.00 0.00 0.25  0.68 0.67 0.78 0.50 0.20 0.55 0.43 0.47 1.00 0.52 0.52 0.62 0.40 0.60 0.46 0.80 0.39 0.58 0.46 0.68 0.40 0.54 0.71 0.68 0.80 0.45  -2  0.44 0.30 0.74 0.53 0.78 0.50  T A B L E 5 -

The second such  system found (Seyfert 1948a, 1948b) also contained a discordant galaxy. In 1968 Sargent discovered yet another discordant redshift in the compact chain of galaxies VV172 (Vorontsov-Vel'yaminov 1959). Two hypotheses were advanced to explain these discordant groups. Either the discordant galaxies are interlopers (foreground or background field galaxies seen projected on the group), or they are physically associated with the other galaxies in the group. The former (projection) hypothesis is consistent with the "cosmological" interpretation that galaxy redshifts are due to the expansion of the universe. The latter hypothesis requires a non-cosmological explanation of at least the redshift of the discordant galaxy.  46  Support for the non-cosmological interpretation comes from two arguments: A number of authors (Arp 1973; Arp and Lorre 1976, Sulentic and Arp 1983, Sulentic and Lorre 1983) have presented evidence which they interpret as indicating physical interaction between the discordant galaxy and other group members. However, this remains controversial because of the difficulty of establishing a clear connection between the discordant galaxy and the rest of the group. Alternatively, it has been suggested that the number of such systems is much too large to be the result of chance projections of unrelated foreground or background galaxies (Burbidge and Burbidge 1961b). It is this latter argument that we address here. Burbidge and Burbidge (1961b) estimated that the probability of the discordant galaxy in Stephan's Quintet being a chance projection was less that 0.1%. Later, however, Burbidge and Sargent (1971) concluded that explanation of discordant galaxy redshifts by the projection hypothesis "might be possible". From a systematic survey for compact galaxy triplets, quartets, and quintets, Rose (1977) concluded that the number of compact systems is large enough to explain the observed discordant redshift groups. However, Sulentic (1983) argued that this survey overestimates the surface density of systems like Stephan's Quintet, Seyfert's Sextet, and VV172 by an order of magnitude. He thus concluded that the discordant members of these groups are not chance projections. The data on Hickson's compact groups and their environments presented in this thesis allow us to quantitatively assess the probability that discordant galaxies are chance projections. The key to this is the well-defined uniform selection criteria for the sample, which makes statistical analysis possible.  47  5.2  Analysis  We select as our sample the original sample of compact groups as described by Hickson (1982), for which the most complete data are available. This sample contains 64 quartets, 25 quintets, and 11 groups with more than 5 members. As before, we define a discordant galaxy as one whose redshift differs by 1000 k m s  - 1  or more  from the median of those of the other group members. Changing this value by 200 km s  - 1  either way has no effect on our result. Of the 30 quartets with complete  redshifts (all catalogued group members) 4 contain a single discordant galaxy. Of the 10 quintets with complete redshifts, 4 contain a single discordant galaxy and one contains two discordant galaxies (with comparable redshifts). No quartet with complete redshift information contains more than one discordant galaxy. To determine the number of quintets with one discordant galaxy expected by chance, we consider the surface density of field galaxies surrounding the 26 accordant redshift quartets with complete velocity data. From the galaxy counts described in Chapter 4, the mean surface density of field galaxies was determined. Many groups showed a slight surface density enhancement close to the group. These may be associated galaxies which may have a similar redshift to the group. In order to estimate the surface density of discordant redshift galaxies, we consider the counts in inner (R < 0.5/r Mpc) and outer (0.5/r < R < 1.125ft Mpc) regions. (R is 1  1  -1  the distance between the field galaxy and the centroid of the group.) If we assume that discordant galaxies in the inner region have the same surface density as the galaxies in the outer region, the ratio of the outer to inner surface densities gives an estimate of the fraction of galaxies near the group which have discordant redshifts.  48  This is similar to the technique used by Sulentic (1987) to estimate the fraction of discordant redshifts in interlopers. To determine the probability that a chance projection of a field galaxy on an accordant quartet would produce a quintet with one discordant redshift, MonteCarlo simulations were performed for each of the 26 accordant quartets as follows: The four group galaxies were assigned their observed positions and magnitudes, and then field galaxies were placed at random within a circle of radius 40 times that of the group radius with a mean surface density equal to that observed in the inner region. A magnitude was assigned to each field galaxy by random selection from the distribution of observed field galaxy magnitudes for that quartet. The program then checked to see if a quintet existed which satisfied the compact group selection criteria.  This was repeated 100,000 times for each quartet and the probability  (fraction of successes) was recorded. This fraction was then multiplied by the ratio of outer/inner field galaxy surface densities to give the probability of forming a discordant redshift quintet from the quartet. From our Monte-Carlo simulations for the 26 accordant quartets we find that the mean probability of forming a quintet by chance from a quartet and a field galaxy is 0.160. Since 86.7% (26 of 30) of the quartets with complete velocities have accordant redshifts and Hickson's catalog contains 64 quartets, the expected number of quintets containing one field galaxy is 0.160 x 0.867 x 64 = 8.85. This is 35.4% of the total number (25) of quintets in the catalog. For the 10 quintets with complete velocities (of which at least four are accordant) the expected number of groups which have a discordant redshift field galaxy according to the projection hypothesis is 3.5. We observe that 4 of the 10 have one discordant redshift, in good  49  agreement with the prediction.  5.3  Discussion  The above analysis shows that the number of quintets with discordant redshifts in a large homogeneous sample of compact groups is consistent with the hypothesis that these are chance projections of field galaxies on physically dense quartets. How do we reconcile this with previous contradictory results? Sulentic (1987) also counted galaxies in fields surrounding these groups. Although his selection criteria are somewhat different than our, our calculated surface densities are comparable. He calculated the expected number of discordant quintets from the formula N  5  = N aA  (1)  4  where 7V is the number of quartets, a is the average field galaxy surface density 4  and A is the average quartet area. From this formula he obtained N = 0.8, much 5  less than our result. The discrepancy arises largely because equation (1) does not correctly account for the selection criteria of the groups. It gives the expected number of quintets formed by superposition of a field galaxy within the circle enclosing the four members of a quartet. However, we can also make a quintet if the field galaxy lies outside the quartet, provided that the selection criteria of mean surface brightness and isolation hold for the quintet. The area of the quintet can thus be significantly larger than that of the original quartet, increasing the probability of discordant quintets. In order to apply Sulentic's criterion, one must consider only those groups  50  in which the discordant galaxy falls within the accordant quartet. We estimated the probabilities for an "internal" discordant galaxy to occur in each of the 26 accordant quartets by multiplying the quartet area by the outer field galaxy density. Averaging these probabilities we find a mean probability of 0.0281. Thus, as above, the expected number of "internal" discordant quintets is 0.0281 x 0.867 x 64 = 1.561. Since there are 25 quintets in the catalog, the probability of any one being internal and discordant is 1.561/25 = 0.0624. In the 10 quintets with complete redshifts we find 3 with an internal discordant galaxy. The probability of observing 3 or more in 10 under the projection hypothesis is (from the binomial distribution)  Thus there is a ~ 2% probability of obtaining the observed number of internal discordant quintets. This is admittedly small, but certainly not small enough to justify rejecting the hypothesis. We expect that further redshifts (which we are now attempting to obtain with larger telescopes) will provide a more definitive test of Sulentic's criterion. There is another effect that causes both Sulentic's criterion and our method to underestimate the number of discordant redshift quintets. Quartets which fail the surface brightness criterion by a small margin and are thus excluded from the catalog may be included if the light added by a fifth (field) galaxy is sufficient to enable the resulting quintet to pass the surface brightness criterion. By considering only quartets it the catalog we underestimate the number of possible host quartets, and consequently the number of discordant quintets. This effect may not be large, however, as none of the four discordant quintets found so far would be excluded by removing the discordant member.  51  In addition to the four observed quintets with one discordant velocity we observe one quintet with two discordant (greater) velocities. This may be explained by the chance superposition of two background galaxies on a foreground triplet. In this case we note that the redshift of the two discordant galaxies are themselves accordant, and that this pair fall outside the circle enclosing the accordant triplet. It therefore seems plausible that this group consists of a background double projected near a foreground triple. Even if clustering is ignored, the chance probability of making a group that includes two field galaxies is not small.  Extending our  Monte-Carlo simulations we find that the probability of making a sextet by chance superposition of two field galaxies on the 26 accordant quartets is only five times less than the chance of making a quintet. From this we conclude that the existence of a single quintet with two discordant galaxy redshifts is also consistent with the projection hypothesis.  52  Chapter 6 S U M M A R Y  A N D  CONCLUSIONS  We have presented new data on a large homogeneous sample of compact groups. These include photometric galaxy magnitudes and accurate Hubble classifications. These data have enabled us to remove misclassified objects from Hickson's original catalog and to make other minor membership revisions. We have examined the completeness of this catalog with group magnitude and galactic latitude and provide formulae for completeness corrections. The environments of these groups have also been searched on the Palomar Sky Survey Prints, with the identification of 3889 galaxies within 1.125h  -1  Mpc of  97 groups. We present positions, and estimated magnitudes, major and minor axis lengths and Hubble types for all of these field galaxies. We find that 78% of the groups show no significant excess of field galaxies v/ithin 0 . 5 h  -1  Mpc. This indicates that most of these compact groups are isolated  53  systems, not associated with loose groups or clusters. Roughly 50% of the galaxies in compact groups are gas rich, being classified as spiral or irregular galaxies. This is a smaller fraction than the 59% found for the field galaxies. For the 22% of the compact groups which do show a significant excess of nearby field galaxies, the difference is even larger, with 44% of the group galaxies being spiral, compared to 64% for the field galaxies. This also supports the view that most groups are dense dynamical entities and not chance alignments in loose groups. Several strong correlations were found between galaxy type and properties of the group in which it resides. These include morphological concordance between galaxies within a group, and a strong correlation between galaxy type and group optical luminosity, and more significantly, group velocity dispersion. Groups with higher velocity dispersion contain fewer spiral galaxies. This is counter to the result expected if galaxy morphology is being significantly modified by dynamical evolution. Dynamical processes such as mergers are expected to destroy spiral galaxies and produce elliptical galaxies. However, these processes occur more rapidly when galaxy velocities are low. We conclude that the morphological types of galaxies in compact groups are strongly influenced by the environment, and that the greatest influence probably occurs at the time of galaxy formation. Finally, we have examined the question of discordant redshifts in compact groups. By computing the probability of a field galaxy being projected in or near a galaxy quartet, we estimate the expected number of galaxy quintets containing a discordant redshift galaxy. As this estimate is very close to the number actually ob-  54  served, we conclude that discordant redshifts can be explained by chance projections of unrelated field galaxies. There is clearly far more work to be done before we reach a satisfactory understanding of the nature, behavior and significance of these small groups. Careful photometric studies will reveal the degree, and effect of galaxy interactions in these groups, leading to a better understanding of the dynamical evolution of galaxies, star formation, and active galactic nuclei. Dynamical studies will provide information on the merger rate, and dark matter associated with galaxies. Ultimately we will learn more about the process of galaxy formation itself. Even now, these groups provide a unique laboratory with which to gain insight into the fascinating and often unexpected behavior of galaxies subject to strong gravitational perturbations and collisions.  55  BIBLIOGRAPHY Ambartsumyan, V .
