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.
