About half the galaxies in the Universe are found in groups and clusters, complexes where typically half the member galaxies are packed into a region ≲1 Mpc across. Groups and clusters no longer expand with the cosmic flow: mutual gravitational attraction is strong enough that the galaxies are moving inward, or have already passed through the core ...

Dark Matter and Baryons in Groups and Clusters of Galaxies
2002We investigate how the properties of the dark matter and baryons in groups and clusters of galaxies depend on the mass of such structures. While the density profiles of dark matter are approximatively self-similar (i.e., their shape do not depend on the mass scale), those of the gas (observable through its copious X-ray emission) become shallower for ...

Compact Stellar Systems in Galaxy Clusters and Groups
Compact stellar systems (CSSs) are spheroidal collections of between several thousand and tensof millions of stars, found through wide field point source surveys in galaxy clusters. At leastan order of magnitude fainter and smaller than dwarf galaxies, CSSs are potential fossil recordsof the galaxy cluster assembly process and may partly account for ...openaire +2 more sources
