CDM and baryons as distinct fluids in a linear approximation for the growth of structure

De, Soma; Dent, James B.; Krauss, Lawrence

Description

A single fluid approximation which treats perturbations in baryons and dark matter as equal has sometimes been used to calculate the growth of linear matter density perturbations in the Universe. We demonstrate that properly accounting for the separate gr
