Title: Into the darkness: Predicting the distribution of dark matter in our Galaxy

Abstract: Dark matter is the dominant form of matter in the universe, but its nature is still unknown. If it is the lightest supersymmetric partner of a known particle, annihilation radiation of dark matter in the halo of the Milky Way should produce gamma-rays at a level which may soon be observable. However, predictions for the detection prospects of dark matter rely on an accurate understanding of the matter distribution in the Galaxy, down to very small scales. In my talk, I will review recent results from high-resolution simulations of cosmic structure formation that provide an unprecedentedly detailed view of dark matter clustering and lead to new suggestions for the best strategy to find dark matter in the Milky Way. I also discuss new findings about the clumpiness of dark matter halos, and the abundance and internal structure of their subhalos.
