Abstract
From the Main galaxy data of the Sloan Digital Sky Survey Data Release 10 (SDSS DR10), we construct two volume-limited samples with the luminosity −20.5 ≤Mr ≤−18.5 and −22.5 ≤Mr ≤−20.5, respectively, and explore the dependence of the clustering properties of galaxies on galaxy age by cluster analysis. Statistical analyses in two volume-limited Main galaxy samples can reach the same conclusions: young galaxies preferentially form isolated galaxies, close pairs and small groups at all scales, whereas old galaxies preferentially inhabit dense groups and clusters.
