Dark Matter Spikes Around Kerr Black Holes

The particle dark matter paradigm is powerful because it provides complementary approaches to investigate theoretical models: direct and indirect detection, as well as collider production. Of these methods, indirect detection is the least clean, as it hinges on a precise understanding of both the small scale particle interactions and the large scale dark matter distributions. In particular, localized dark matter "clumps" can lead to large effects on gamma ray fluxes. In this talk, I will talk about one such clump which could be present in galaxies that have not gone through many mergers - the adiabatic spike around a black hole. Some general advice on graduate school survival and old-man-cloud-yelling may also be present.
