The aim of this thesis is to study the evolution of the distribution of baryons in the Universe. It is used a Schrödinger equation approach which had already proven successful in the study of Cold Dark Matter. Both a semi-analytical (via quantum perturbation theory and limited to scales bigger than the Jeans wavelength) and a numerical study ( Strang time-splitting approximation) are presented. In addition we extended a previous study on a new candidate for DM, fuzzy DM, considering the possibility of a velocity dispersion modelled as a gas pressure.

Abstract
The aim of this thesis is to study the evolution of the distribution of baryons in the Universe. It is used a Schrödinger equation approach which had already proven successful in the study of Cold Dark Matter. Both a semi-analytical (via quantum perturbation theory and limited to scales bigger than the Jeans wavelength) and a numerical study ( Strang time-splitting approximation) are presented. In addition we extended a previous study on a new candidate for DM, fuzzy DM, considering the possibility of a velocity dispersion modelled as a gas pressure.File in questo prodotto:
