CHEX-MATE: Morphological analysis of the sample

In this work, we performed an analysis of the X-ray morphology 118 CHEX-MATE (Cluster HEritage project with XMM-Newton - Mass Assembly and Thermodynamics at Endpoint structure formation) galaxy clusters, aim to provide a classification their dynamical state. To investigate link between appearance state, considered four morphological parameters: surface brightness concentration, centroid shift, second- third-order power ratios. These indicators result be: strongly correlated each other, powerful in identifying disturbed relaxed population, characterised by unimodal distribution not influenced systematic uncertainties. order obtain continuous objects, combined these parameters single quantity, M, which represents grade relaxation system. On basis M value, identified most extreme systems sample, finding 15 very 27 clusters. From comparison previous on selected samples, confirmed that Sunyaev-Zeldovich (SZ) clusters tend be more disturbed. Finally, applying our simulated found general agreement observed results, only exception concentration. This latter behaviour, is partially related presence particles high smoothed-particle hydrodynamics density central regions due action idealised isotropic thermal Active Galactic Nuclei (AGN) feedback.
