Using dark matter halos traced by galaxy groups selected from the Sloan Digital Sky Survey Data Release 4, we find that about 1/4 of the faint galaxies ($\rmag >-17.05$, hereafter…
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.…
