We analyze the velocity dispersions of 79 galaxy clusters having at least 30 galaxies with available redshifts. Different methods for estimating the velocity dispersions are considered, and the distribution function of cluster velocity dispersions is compared with the CDM predictions.

Abstract
We analyze the velocity dispersions of 79 galaxy clusters having at least 30 galaxies with available redshifts. Different methods for estimating the velocity dispersions are considered, and the distribution function of cluster velocity dispersions is compared with the CDM predictions.File in questo prodotto:
