Clusters of Galaxies in the 2dF Galaxy Redshift Survey
Roberto De Propris, Warrick J. Couch, the 2dFGRS Team
Abstract
The 2dF Galaxy Redshift Survey has obtained 135,000 redshifts for galaxies in two broad strips. Here we present the first results of a 3-dimensional search for galaxy clusters based on known 2-dimensional compilations. We derive new redshifts and velocity dispersions for clusters, assess the level of contamination in the sample, analyze the accuracy of photometric redshift estimates and study the space distribution of clusters.
