Institute for Advanced Study Informal Astrophysics Seminar

I will review recent advances in the modeling of galaxy bias in the context of galaxy evolution. The connection between galaxies and dark matter halos contains significant information for understanding how galaxies form and evolve. I will focus on the red sequence, using the halo model to constrain the relative importance of different physical mechanisms for quenching star formation and placing galaxies on the red sequence. I will use a combination of SDSS and COSMOS data to show how these mechanisms have evolved over the redshift baseline z=1 to 0.
