We consider a sample of about 50 distant clusters at z> 0.15 (<z>=0.3), each cluster having at least 10 galaxies and evaluate in a homogeneus way cluster velocity dispersions and optical virial masses. We apply the same procedures already successfully applied on a sample of nearby clusters in order to properly analyze the possible dynamical evolution of galaxy clusters. We do not find any evidence for an evolution of cluster properties.

Abstract

We consider a sample of about 50 distant clusters at z> 0.15 (=0.3), each cluster having at least 10 galaxies and evaluate in a homogeneus way cluster velocity dispersions and optical virial masses. We apply the same procedures already successfully applied on a sample of nearby clusters in order to properly analyze the possible dynamical evolution of galaxy clusters. We do not find any evidence for an evolution of cluster properties.
