Recent Dynamical Relaxation of Galaxy Clusters: Evidence for a Low-$\Omega_m$ Universe

Astrophysics 2009-11-07 v1

Abstract

We argue that there has been substantial evolution in the ellipticity of rich galaxy clusters between 0 < z < 0.1, and suggest that this is additional evidence for a low matter-density Universe.
