Description

Recently a generalized Chaplygin gas has been proposed as a unifying solution to the dark energy and dark matter problems. In this work, we will study the density perturbations of a universe filled with radiation, baryonic matter and the Chaplygin gas fluid and analyse the implications on large-scale structure. We will then compare our model results with power spectrum of the observable universe.
