Alignments of Group Galaxies with Neighboring Groups
Yougang Wang, Changbom Park, Xiaohu Yang +2
Using a sample of galaxy groups found in the Sloan Digital Sky Survey Data Release 4, we measure the following four types of alignment signals: (1) the alignment between the distri…
Modeling Galaxy-Galaxy Weak Lensing with SDSS Groups
Ran Li, H. J. Mo, Zuhui Fan +4
We use galaxy groups selected from the Sloan Digital Sky Survey (SDSS) together with mass models for individual groups to study the galaxy-galaxy lensing signals expected from gala…
Ongoing Assembly of Massive Galaxies by Major Merging in Large Groups and Clusters from the SDSS
Daniel H. McIntosh, Yicheng Guo, Jen Hertzberg +4
We investigate the incidence of major mergers creating >10e11 Msun galaxies in present-day groups and clusters more massive than 2.5e13 Msun. We identify 38 pairs of massive galaxi…
Galaxy Groups in the SDSS DR4: I. The Catalogue and Basic Properties
Xiaohu Yang, H. J. Mo, Frank C. van den Bosch +3
We use a modified version of the halo-based group finder developed by Yang et al. to select galaxy groups from the Sloan Digital Sky Survey (SDSS DR4). In the first step, a combina…
Towards a Concordant Model of Halo Occupation Statistics
Frank C. van den Bosch, Xiaohu Yang, H. J. Mo +6
We use the conditional luminosity function (CLF) and data from the 2dFGRS to constrain the average relation between light and mass in a LCDM cosmology with Omega_m=0.23 and sigma_8…
