Structural Properties of Central Galaxies in Groups and Clusters
Yicheng Guo, Daniel H. McIntosh, H. J. Mo +6
Using a representative sample of 911 central galaxies (CENs) from the SDSS DR4 group catalogue, we study how the structure of the most massive members in groups and clusters depend…
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…
