Probing Dynamical Dark Energy with Press-Schechter Mass Functions

TL;DR

This paper investigates how different dynamical dark energy models influence the formation of non-linear dark matter structures, using the Press-Schechter mass function to connect theoretical models with observational data.

Contribution

It provides an analysis of the impact of dynamical dark energy on dark matter halo formation, offering insights into distinguishing dark energy models through structure formation observations.

Findings

Dynamical dark energy models alter the predicted halo mass functions.

The Press-Schechter formalism can be used to probe dark energy properties.

Results help discriminate between different dark energy scenarios.

Abstract

Measurement of accelerated expansion in the Universe led to propose a new cosmic fluid as its cause: dark energy. Its various incarnations offer a wealth of models whose relevance it is important to discriminate via contacts with observations. I will present my investigations on the influence of dynamical dark energy models on the formation of non-linear dark matter structures. In particular, I will focus on structures traced by the mass function of dark matter haloes.
