TL;DR: In this paper, the authors used the HELLAS2XMM 1df (1 degree field) survey data to evaluate the fraction of X-ray absorbed (log NH > 22) Active Galactic Nuclei (AGN) in the 2−10 keV flux range 0.8−20 × 10 −14 erg cm −2 s −1.

TL;DR: The XMM-Newton cluster outskirts project (X-COP) as discussed by the authors targets the outer regions of a sample of 13 massive clusters (R > R500) in the redshift range 0.04-0.1 at uniform depth.

TL;DR: In this paper, an XMM-Newton analysis of the X-ray spectra of 39 clusters of galaxies at 0.15-0.4 r500 was presented, where the most significant de veiation from no evolution (at a 90% confidence level) is observed by consid ering the emission from the whole cluster (r < 0.6r500), which can be parametrized as Z ∝ (1 + z) −0.8±0.5.
