Environmental Enhancement of Loose Groups around Rich Clusters of Galaxies

  • Published 2002


We have studied the properties of Las Campanas Loose Groups (Tucker et al. 2000) in the neighbourhood of rich (Abell, APM and X-ray) clusters of galaxies. These loose groups show strong evidence of segregation measured in terms of the group richness and the group velocity dispersion: loose groups in the neighbourhood of a rich cluster are typically 2.5… (More)
