Gaia and the Galactic halo

In this talk, the Gaia data is used to study the properties of the Milky Way stellar halo. I will present new constraints on the halo spin, the halo accretion history, measurements of the tangential motion of the largest halo substructures such as the Sgr stream and the Monoceros Ring, the detection of multiple new streams in the Solar neighbourhood as well as the discovery of new faint satellites. All of this with the Gaia DR1. Imagine what you will be able to do with the Gaia DR2 in less than one month.
