A wealth of astronomical data indicate the presence of mass discrepancies in the Universe.
The motions observed in a variety of classes of extragalactic systems exceed what can be …

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 compare the results of Eulerian hydrodynamic simulations of cluster formation against
virial scaling relations between four bulk quantities: the cluster mass, the dark matter velocity …

We present cosmological parameter constraints obtained from galaxy clusters identified by
their Sunyaev–Zel'dovich effect signature in the 2500 square-degree South Pole Telescope …

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 present the compilation and properties of a meta-catalogue of X-ray detected clusters of
galaxies, the MCXC. This very large catalogue is based on publicly available ROSAT All Sky …

▪ Abstract The Sunyaev-Zel'dovich effect (SZE) provides a unique way to map the large-
scale structure of the universe as traced by massive clusters of galaxies. As a spectral …

Using semi-analytic models of galaxy formation, we investigate galaxy properties such as
the Tully-Fisher relation, the B-and K-band LFs, cold gas contents, sizes, metallicities and …

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 A new X-ray–selected and X-ray flux–limited galaxy cluster sample is
presented. Based on the ROSAT All-Sky Survey, the 63 brightest clusters with galactic …
