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 ...

Clusters and groups of galaxies
2014Galaxies are not uniformly distributed in space, but instead show a tendency to gather together in galaxy groups and clusters of galaxies. This effect can be clearly recognized in the projection of bright galaxies on the sky (see Figs. 6.1 and 6.2). The Milky Way itself is a member of a group, called the Local Group (Sect.

Shapes and Galaxy Flows Around Clusters and Groups of Galaxies
2007We present results from three recent works, one on the shapes of groups in the 2dFGRS and SDSS catalogues [5], and the others on the dynamics around clusters and groups of galaxies, in a theoretical framework [6] and from observational data [1]. Our results for the shapes of groups of galaxies indicate that more massive groups are more elongated than ...

Galaxies Including Globular Clusters and Local Group
1975According to Baade (1944) the stellar population in the central bulge of M31 resolves at the same magnitude level as do the globular clusters associated with that galaxy. This observation led Baade to conclude that the nuclear bulge of the Andromeda Nebula consists of globular cluster-like stars.
