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 …

▪ Abstract Modified Newtonian dynamics (MOND) is an empirically motivated modification of
Newtonian gravity or inertia suggested by Milgrom as an alternative to cosmic dark matter …

We introduce the Cluster-EAGLE (c-eagle) simulation project, a set of cosmological
hydrodynamical zoom simulations of the formation of 30 galaxy clusters in the mass range of …

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 constraints on the mean dark energy density, ΩX and dark energy equation of
state parameter, w X, based on Chandra measurements of the X-ray gas mass fraction in 26 …

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 …

We present a 90 per cent flux-complete sample of the 201 X-ray-brightest clusters of
galaxies in the northern hemisphere (δ≥ 0°), at high Galactic latitudes (ǀ b ǀ≥ 20°), with …

We review the X-ray spectra of the cores of clusters of galaxies. Recent high resolution X-ray
spectroscopic observations have demonstrated a severe deficit of emission at the lowest X …

We describe and discuss the selection procedure and statistical properties of the galaxy
sample used by the Calar Alto Legacy Integral Field Area (CALIFA) survey, a public legacy …

We present Chandra X-ray observations of the Hydra A cluster of galaxies, and we report the
discovery of structure in the central 80 kpc of the cluster's X-ray–emitting gas. The most …
