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…
The Correlation of Star Formation Quenching with Internal Galaxy Properties and Environment
Taysun Kimm, Rachel S. Somerville, Sukyoung K. Yi +8
We investigate the correlation of star formation quenching with internal galaxy properties and large scale environment (halo mass) in empirical data and theoretical models. We make…
Environmental Effects on Satellite Galaxies: The Link Between Concentration, Size and Colour Profile
Simone M. Weinmann, Guinevere Kauffmann, Frank C. van den Bosch +5
Using the SDSS DR4 group catalogue of Yang et al. (2007), we investigate sizes, concentrations, colour gradients and surface brightness profiles of central and satellite galaxies.…
The Rise and Fall of Galaxy Activity in Dark Matter Haloes
Anna Pasquali, Frank C. van den Bosch, H. J. Mo +2
We use a SDSS galaxy group catalogue to study the dependence of galaxy activity on stellar mass, halo mass, and group hierarchy (centrals vs. satellites). We split our galaxy sampl…
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…
Satellite Ecology: The Dearth of Environment Dependence
Frank C. van den Bosch, Anna Pasquali, Xiaohu Yang +4
Using the Sloan Digital Sky Survey (SDSS) galaxy group catalogue of Yang et al. (2007), we study the average colour and average concentration of satellite galaxies as function of (…
