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…
The dependence of dark halo clustering on the formation epoch and the concentration parameter
Y. P. Jing, Yasushi Suto, H. J. Mo
We examine the age-dependence of dark matter halo clustering in an unprecedented accuracy using a set of 7 high-resolution cosmological simulations each with particles.…
The Accretion and Cooling of Preheated Gas in Dark Matter Halos
Yu Lu, H. J. Mo
(abridged) We use a one-dimensional hydrodynamical code to investigate the effects of preheating on gas accretion and cooling in cold dark matter halos. In the absence of radiative…
