Dark Matter in Milky Way Satellite Galaxies

Using detailed observations of the Milky Way substructure to study wide-range of questions in galaxy formation and dark matter physics – has become a rich field over the past decade. How well we can measure the dark matter content of Milky Way satellite galaxies using the stellar kinematic information plays an important role for interpolating/answering these questions. I will discuss issues from two directions and address what their future aspects are : (1) The implied stellar mass – halo mass relation at the faint end and how it affects our understandings of Milky Way formation history and dark matter physics  (2) What (and how well) we can learn about dark matter properties from Milky Way satellite galaxies.
