Titel: Gaia’s view of the Milky Way halo
It was always hoped that one day we would be able to use Gaia data to pin down the matter distribution in the Milky Way, measure the Galactic accretion history, find new previously unseen dwarf galaxies with unprecedentedly low surface brightnesses and track narrow stellar streams to gauge masses of Dark Matter sub-halos. I will show that all of these hopes came true with the last year’s Gaia Data Release 2.
