Luminous red galaxy pairs from the Sloan Digital Sky Survey Data Release 3
Abstract:By using cluster analysis, we select three luminous red galaxy (LRG) pair samples and study their various properties. We find that LRG pair samples identified at different radii have the same properties; there is a tendency for pair galaxies to have similar luminosities and sizes. Additionally, LRG pairs have the same properties as the whole LRG sample and isolated LRGs.
