u - r Color Dependence of Galaxy Clustering in the Main Galaxy Sample of SDSS DR10

摘要

Using two volume-limited Main galaxy samples of the Sloan Digital Sky Survey Data Release 10 (SDSS DR10), we investigate u - r color dependence of clustering properties of galaxies. We can get the same statistical conclusion in two volume-limited Main galaxy samples: blue galaxies preferentially form isolated galaxies, close pairs, and small groups at all scales, whereas red galaxies preferentially inhabit dense groups and clusters.
