The Cluster Environments of Quasar Groups
Abstract
Quasars are rare astronomical objects, and quasar pairs, triplets and larger groupings are even rarer. The presence of several quasars in the same small volume of space might therefore indicate a region that is exceptionally rich in galaxies, and hence groups of quasars could serve as ueful beacons for identifying distant clusters or protoclusters of galaxies. With this motivation, we compare the cluster environments of single versus multiple quasar systems using data from the Sloan Digital Sky Survey.
