Constraining the Distribution of Dark Matter Lumps Around the Milky Way Using Tidal Debris
Published online by Cambridge University Press: 26 May 2016
Abstract
Dwarf galaxies that fall into the Milky Way's potential are tidally disrupted. Their tidal tails are one of the most powerful probes of the mass distribution in the Galaxy. If the distribution of dark matter in the Galaxy is lumpy, then these lumps will scatter stars in the stream and alter its shape. We describe our approach to using the tidal debris to constrain substructure in the Galaxy halo.
