An extensive spectroscopic study of 10 rich southern X-ray clusters of galaxies is presented. Between 40 and 200 redshifts have been obtained in the field of each of the clusters, which cover a wide range of morphological types and richnesses. Applying rigorous statistical analyses to the total data base of 1000 precise radial velocities provides the necessary information to undertake a thorough dynamical investigation of these individual clusters and of cluster systems in general. 92 refs.read more

The Mass Function of an X-Ray Flux-Limited Sample of Galaxy Clusters
TL;DR: In this article, a new X-ray-selected and Xray flux-limited galaxy cluster sample is presented, based on the ROSAT All-Sky Survey, the 63 brightest clusters with galactic latitude |bII|? 20? and flux fX(0.1-2.4keV)? 2? 10-11ergss-1cm-2 have been determined utilizing intracluster gas density profiles, derived mainly from ROSAT PSPC pointed observations, and gas temperatures, as published mainly from ASCA observations.

TL;DR: The 2MASS XSC as mentioned in this paper contains nearly a million galaxies with K_s ≤ 13.5 mag and is essentially complete and mostly unaffected by interstellar extinction and stellar confusion down to a galactic latitude of |b| = 5° for bright galaxies.

Optical mass estimates of galaxy clusters
TL;DR: In this paper, the mass of 170 nearby clusters (z ≤ 0.15) is computed by applying the virial theorem to the member galaxies, assuming that mass follows the galaxy distribution and that clusters are not far from a situation of dynamical equilibrium.
