Title:The Darkest Galaxies

Abstract:In the past three years, fourteen Milky Way satellite galaxies have been discovered, more than doubling the known population. These newly discovered ``ultra-faint'' galaxies have emerged as the least luminous and most dark matter-dominated galaxies in the known Universe. They are dramatically reshaping our understanding of galaxy formation and may hold the keys to deciphering the nature of dark matter. I will review our current understand of the ultra-faint galaxies, focusing on the constraints these objects provide on dark matter.
