Exploring the mass and redshift dependence of the cluster pressure profile with stacks on thermal SZ maps

We provide novel constraints on the parameters defining the universal pressure profile (UPP) within clusters of galaxies, and explore their dependence on the cluster mass and redshift, from measurements of Sunyaev-Zel'dovich Compton-\(y\) profiles. We employ both the \(\textit{Planck}\) 2015 MI...

Description
Summary:We provide novel constraints on the parameters defining the universal pressure profile (UPP) within clusters of galaxies, and explore their dependence on the cluster mass and redshift, from measurements of Sunyaev-Zel'dovich Compton-\(y\) profiles. We employ both the \(\textit{Planck}\) 2015 MILCA and the ACT-DR4 \(y\) maps over the common \(\sim 2,100\,\text{deg}^2\) footprint. We combine existing cluster catalogs based on KiDS, SDSS and DESI observations, for a total of 23,820 clusters spanning the mass range \(10^{14.0}\,\text{M}_{\odot}
