The universe's biggest galaxies have both vast atmospheres and supermassive central
black holes. This article reviews how those two components of a large galaxy couple and …

The co-evolution between supermassive black holes and their environment is most directly
traced by the hot atmospheres of dark matter halos. The cooling of the hot atmosphere …

We investigate the physical mechanisms that shape the luminosity function of galaxies in
hierarchical clustering models. Beginning with the mass function of dark matter halos in the …

The most successful cosmological models to date envision structure formation as a
hierarchical process in which gravity is constantly drawing lumps of matter together to form …

We present detailed comparisons of the intracluster medium (ICM) in cosmological Eulerian
cluster simulations with deep Chandra observations of nearby relaxed clusters. To assess …

We present radial entropy profiles of the intracluster medium (ICM) for a collection of 239
clusters taken from the Chandra X-ray Observatory's Data Archive. Entropy is of great …

Galaxy groups are more than an intermediate scale between clusters and halos hosting
individual galaxies, they are crucial laboratories capable of testing a range of astrophysics …

We present global multidimensional numerical simulations of the plasma that pervades the
dark matter haloes of clusters, groups and massive galaxies (the 'intracluster medium'; ICM) …

Taking advantage of the all-sky coverage and broadfrequency range of the Planck satellite,
we study the Sunyaev-Zeldovich (SZ) and pressure profiles of 62 nearby massive clusters …

Using a sample of ten nearby (), relaxed galaxy clusters in the temperature range [2–9], we
have investigated the scaling relation between the mass at various density contrasts () and …
