Description
Cluster outskirts are an area of great interest as they contain a wealth of information as to how the hot intracluster medium (ICM) forms and contributes to the growth of large scale structures. With the advent of Athena, measurements of the ICM should be possible beyond the virial radius. To this end, we present the metallicity profiles and distribution of different metals for the C-EAGLE simulation, a suite of 30 massive galaxy clusters (M500 > 10^14 Msun), focussing on the cluster outskirts, r > R200.
We also present the CELR (C-EAGLE at low resolution) sample, for which we have investigated how using mock X-ray temperatures combined with mock X-ray density profiles leads to more biased estimates for the mass of more massive clusters. We have found that this bias can be improved by including a model for non-thermal pressure, but a mass dependence of the bias is still seen.
