The Stellar Mass Dependence of Clustering Properties of SDSS Galaxies
並列摘要
Using the volume-limited Main Galaxy Sample of the Sloan Digital Sky Survey Data Release 6 (SDSS DR6), we explore the stellar mass dependence of clustering properties by the friends-of-friends algorithm. It is found that low mass galaxies preferentially form isolated galaxies, close pairs, and small groups, while high mass galaxies preferentially inhabit the dense groups and clusters. We also investigate the correlation of the stellar mass with the local environment, and show that high mass galaxies exist preferentially in the densest regions of the universe, while low mass galaxies are located preferentially in low density regions. It is well-known that morphology, color, and star formation activity are correlated with density. So, our results are consistent with stellar mass being correlated with morphological type, color, and star formation activity.
