Description

Galaxy clusters are the largest gravitationally bound objects in our Universe, are dark-matter dominated, and have the baryonic mass component mainly composed by X-ray emitting plasma also observable through Sunayev-Zeldovich effect at millimeter wavelengths. Thus, X-ray (and SZ) data provide a unique view of their structure.
Using data and results from our ongoing Heritage XMM-Newton program CHEX-MATE, I will revise the current observational constraints on the fundamental properties defining the cluster's structure, how these constraints align with the prevailing cosmological paradigm, what are the outstanding issues, and what are our strategies to address them with further to construct a consistent picture of how galaxy clusters form and evolve.
