Luminous red galaxy pairs from the SDSS data release 3
Abstract:Using cluster analysis, we selected three luminous red galaxy (LRG) pair samples and studied their various properties. We found that LRG pair samples, identifying at different radii, have the same properties: there is a tendency for pair galaxies to have similar luminosity and size. Additionally, LRG pairs have the same properties as whole and isolated LRGs.
