Warm dark matter collapse : real space analysis methods Loranger, Jonathan
Abstract
We study the evolution of a warm dark matter and perfect fluid system to determine its behaviour in the linear regime. Comparative analysis is performed between cold dark matter, hot dark matter and warm dark matter approximating each case. Numerical issues causes differences between the warm dark matter approximations and the respective case. Numerical issues that we have been unable to solve prevent the calculation of sufficient k-space modes to study interesting scales. Analytic methods to obtain the real space perturbations and distribution functions are derived.

We study the evolution of a warm dark matter and perfect fluid system to determine its behaviour in the linear regime. Comparative analysis is performed between cold dark matter, hot dark matter and warm dark matter approximating each case. Numerical issues causes differences between the
warm dark matter approximations and the respective case. Numerical issues that we have been unable to solve prevent the calculation of sufficient k-space
modes to study interesting scales. Analytic methods to obtain the real space perturbations and distribution functions are derived.
