Princeton University Dark Cosmos Seminar
Dark Matter in the Smallest Galaxies
Abstract: I will review efforts to infer the amount and spatial distribution of dark matter within the Milky Way's dwarf spheroidal satellites. I will show first results from a large (Magellan/M2FS) spectroscopic survey targeting ten thousand stars within the Fornax dSph. Finally I will present results from fitting flexible surface brightness models to the known dSphs, revealing surprising structural diversity within the dSph population.
