We review the progress in modeling the galaxy population in hydrodynamical simulations of
the ΛCDM cosmogony. State-of-the-art simulations now broadly reproduce the observed …

High resolution X-ray spectroscopy of the hot gas in galaxy clusters has shown that the gas
is not cooling to low temperatures at the predicted rates of hundreds to thousands of solar …

We detect a weak unidentified emission line at E=(3.55–3.57)±0.03 keV in a stacked XMM-
Newton spectrum of 73 galaxy clusters spanning a redshift range 0.01–0.35. When the full …

The radiative cooling timescales at the centers of hot atmospheres surrounding elliptical
galaxies, groups and clusters are much shorter than their ages. Therefore, hot atmospheres …

We investigate the regularity of cluster pressure profiles with REXCESS, a representative
sample of 33 local (z< 0.2) clusters drawn from the REFLEX catalogue and observed with …

Abstract The hot (107 to 108 kelvin), X-ray-emitting intracluster medium (ICM) is the
dominant baryonic constituent of clusters of galaxies. In the cores of many clusters, radiative …

We present gas and total mass profiles for 13 low-redshift, relaxed clusters spanning a
temperature range 0.7-9 keV, derived from all available Chandra data of sufficient quality. In …

We discuss a numerical model for black hole growth and its associated feedback processes
that for the first time allows cosmological simulations of structure formation to self …

We study relation between stellar mass and halo mass for high-mass halos using a sample
of galaxy clusters with accurate measurements of stellar masses from optical and ifrared …

We discuss the measurements of the galaxy cluster mass functions at z≈ 0.05 and z≈ 0.5
using high-quality Chandra observations of samples derived from the ROSAT PSPC All-Sky …
