An explanation of the observed excess emissions in our galaxy using the Axion Quark Nugget dark matter model Sekatchev, Michael

Abstract

Telescope observations of background radiation in the Milky Way point to an anomalous excess in ultraviolet, microwave, and radio signals. The novel Axion Quark Nugget (AQN) dark matter model may provide an interpretation for this as-yet-unexplained excess. Baryonic matter in the galaxy may collide with antimatter AQNs and annihilate, resulting in an emission of a broad spectrum of electromagnetic radiation similar in form to Bremsstrahlung. This project performs the comparison of AQN annihilation radio emissions with the observed radio haze from WMAP, using a Markov chain Monte Carlo method to produce constraints on the AQN mass range and the dark matter density distribution in our Milky Way. Understanding the source(s) of the excess radiation in our galaxy may bring us a step closer to revealing the exact nature of dark matter.
