TL;DR: In this paper, the authors investigate the regularity of cluster pressure profiles with REXCESS, a representative sample of 33 local (z < 0.2) clusters drawn from the this paperLEX catalogue and observed with XMM-Newton.

TL;DR: In this article, the authors investigate the regularity of cluster pressure profiles with REXCESS, a representative sample of 33 local clusters observed with XMM-Newton, and derive an average profile from observations scaled by mass and z according to the standard self-similar model, and find that the dispersion about the mean is remarkably low beyond 0.2R_500, but increases towards the centre.

TL;DR: The MCXC the authors is a meta-catalog of X-ray detected clusters of galaxies, which is based on publicly available ROSAT All Sky Survey-based (NORAS, the authorsLEX, BCS, SGP, NEP, MACS, and CIZA) and serendipitous (160SD, 400SD, SHARC, WARPS, and EMSS) cluster catalogues.

TL;DR: This paper examined the radial entropy distribution and its scaling using 31 nearby galaxy clusters from the Representative XMM-Newton Cluster Structure Survey (REXCESS), a sample in the temperature range 2-9 keV selected in X-ray luminosity only, with no bias toward any particular morphological type.

TL;DR: In this article, the authors examined the radial entropy distribution and its scaling using 31 nearby galaxy clusters from the Representative XMM-Newton Cluster Structure Survey (REXCESS) and found that the observed distributions show a radial and mass-dependent excess entropy that is greater and extends to larger radii in lower mass systems.
