Tracing Galaxy Formation with Stellar Halos I : Methods


If the favored hierarchical cosmological model is correct, then the Milky Way system should have accreted ∼ 100− 200 luminous satellite galaxies in the past ∼ 12 Gyr. We model this process using a hybrid semi-analytic plus N-body approach which distinguishes explicitly between the evolution of light and dark matter in accreted satellites. This distinction… (More)
