The radius, at which a galaxy group stops the Hubble stream, and the group mass: an exact analytical solution

Cosmology and Nongalactic Astrophysics 2019-09-25 v2 Astrophysics of Galaxies

Abstract

The gravitational field of a galaxy group or cluster slows down the Hubble stream and turns it speed to zero at some radius R0R_0. We offer an exact analytical relation between R0R_0 and the mass of the group.
