Abstract

We investigate the correlations between galaxy properties and environment. From the main galaxy sample of the SDSS Data Release 5, we have extracted 11 163 groups at the linking length R_0_=0.2x({bar}n)^-1/3^=1.97Mpc (where {bar}n is the mean number density of galaxies) by the three-dimensional friends-of-friends (FOF) algorithm, where {bar}n is the mean galaxy density, and compare basic properties of member galaxies of main galaxy groups with those of the main galaxy sample and isolated galaxies in each redshift bin.

Keywords
