Galaxy groups and clusters

, 2007
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 ...

Comparison of physical characteristics of globular clusters in groups and clusters of galaxies

EUREKA: Physics and Engineering
This article discusses the problems of the physical properties of globular clusters in galaxy clusters and groups. Observational data of globular clusters in galaxy clusters and individual groups were analyzed.

Mass determination in galaxies, groups of galaxies, and clusters of galaxies

IEEE Transactions on Plasma Science, 1990
Computer simulations of interacting galaxies are used to determine the contribution of halos in disk galaxies. It appears that generally the halo is less massive than the disk. Redshift asymmetries are used to separate binary pairs from optical pairs in catalogs of galaxy pairs.

Estimation of the Hubble constant from the scatter of the fundamental plane distances of groups and clusters of galaxies ($71.1\pm 2.8$ km s$^{-1}$ Mpc$^{-1}$)

Modern astronomy: from the Early Universe to exoplanets and black holes
To determine the peculiar velocities of galaxy clusters relative to the Hubble Flow, we need to measure the distances of galaxy systems using some method that is sensitive to their distances.

Clusters and groups of galaxies

2014
Galaxies 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.
