    Number density profiles of galaxy groups and clusters in the SDSS 

    Norris, Jackson M. (Vanderbilt University. Dept. of Physics and Astronomy, 2008-04-20)
    We use projected number density profiles of galaxy groups to investigate the relationship between galaxy group structure and dark matter structure within halos. We primarily study a specific model of how galaxies populate ...
