Dark matter and structure formation a review

TL;DR

This review discusses different dark matter variants and their influence on cosmic structure formation, including new modifications to the spherical collapse model accounting for dynamical friction and tidal torques.

Contribution

It introduces novel modifications to the spherical collapse model by incorporating dynamical friction and tidal torques, enhancing understanding of structure formation.

Findings

Modified spherical collapse model with dynamical friction

Inclusion of tidal torques effects on collapse dynamics

Improved predictions of structure formation processes

Abstract

This paper provides a review of the variants of dark matter which are thought to be fundamental components of the universe and their role in origin and evolution of structures and some new original results concerning improvements to the spherical collapse model. In particular, I show how the spherical collapse model is modified when we take into account dynamical friction and tidal torques.
