Abstract

We will discuss the estimated densities of dark matter in the central regions of galaxies and discuss their inconsistency with the predictions of cold dark matter only simulations. We will focus on the satellites of the Milky Way to highlight this issue and then explore dark matter with significant self-interactions as a viable alternative. Milky Way satellites also place stringent constraints on WIMP dark matter models in a completely different way through Fermi-LAT observations and we will summarize those results.
