The Dynamic Local Universe

Presented by Dr. Louis Strigari (Texas A&M)

New three-dimensional measurements of the positions and velocities of stars, in particular from the Gaia observatory, have provided unprecedented information on the dynamics of the Milky Way and nearby dwarf galaxies. I will discuss how these observations inform hierarchical structure formation, the Milky Way, the Local Group of galaxies, and the nature of dark matter. I will discuss what we can expect from future Gaia data and astrometric observations.
