The Astrophysical Journal, 2016 ABSTRACT A galaxy group catalog is constructed from the 2MASS Redshift Survey (2MRS) with the use of a halo-based group finder. The halo mass associated with a group is estimated using a “GAP” method based on the luminosity of the central galaxy and its gap with other member galaxies.Xiaohu Yang, Dylan Tweed, Houjun Mo, Houjun Mo, S.
