Clusters of Galaxies: Structure and Dynamics in the Last 8 Gyr

TL;DR

This paper reviews the structure and dynamics of galaxy clusters over the last 8 billion years, emphasizing their role in understanding dark matter through observational and simulation comparisons.

Contribution

It compiles past and recent findings on galaxy cluster mass distributions, highlighting their importance in dark matter research and cosmological studies.

Findings

Galaxy clusters are dark matter dominated and serve as key cosmological probes.

Observational mass distributions are compared with simulations to constrain dark matter properties.

Recent results improve understanding of cluster evolution and dark matter nature.

Abstract

Clusters of galaxies, being dark matter dominated, have long been and still are the ideal cosmological targets to study the nature of dark matter. Constraints on the nature of dark matter comes in particular from the observational determination of the distribution of total and baryonic mass in clusters, by comparison with results from cosmological numerical simulations. I present here past and recent results on this research topic.
