The distribution of virial masses for nearby galaxy clusters is presented. The analysis is based on a data-set of 75 clusters, each with >20 members with measured redshifts within 1.5h^-1 Mpc. Having accounted for problems of incompleteness of the data-set, a power is finally fitted to the mass distribution. Constraints on the spectrum of primordial fluctuations are obtained.

Abstract
The distribution of virial masses for nearby galaxy clusters is presented. The analysis is based on a data-set of 75 clusters, each with >20 members with measured redshifts within 1.5h^-1 Mpc. Having accounted for problems of incompleteness of the data-set, a power is finally fitted to the mass distribution. Constraints on the spectrum of primordial fluctuations are obtained.File in questo prodotto:
