Galaxy redshifts in 3 medium-distant clusters.


Abstract (from CDS):

We present results from spectroscopic observations of 3 rich and moderately distant galaxy clusters at the 3.6 m ESO telescope at La Silla. We measured 54 galaxy redshifts in 3 fields centered on the clusters A 3663 and A 3889, which are rich (R=2) and distant (D=6) ACO clusters, and on a new cluster, Cl 0053-37, identified on a deep plate. We present estimates of their velocity dispersion and virial mass. Cl 0053-37 had been noted as a concentration in a poor ACO cluster, S0102, with distance class D=4. We show that Cl 0053-37 is a more distant cluster, connected to a large scale-structure at z∼0.165.
