COLLISIONS AND RELAXATION IN GALAXY CLUSTERS

The rate of close collisions among galaxies in a cluster, and the rates of both gravitational two-body and violent relaxation are shown, in most cases, to be proportional to the Hubble constant. Therefore, the number of collisions or the degree of relaxation attained in one Hubble time are invariant...

Summary:The rate of close collisions among galaxies in a cluster, and the rates of both gravitational two-body and violent relaxation are shown, in most cases, to be proportional to the Hubble constant. Therefore, the number of collisions or the degree of relaxation attained in one Hubble time are invariant to the Hubble constant.
