Astroparticle Physics Seminar

Wyn Evans, "The Sausage, the Sequoia and the Splash"

Europe/Berlin
Description

The Gaia satellite, which is providing the positions, velocities and chemical properties of over a billion stars in the Milky Way Galaxy, is transforming our understanding of Galactic structure. We will present evidence that there were ancient and dramatic collisions between the Milky Way Galaxy and smaller objects, the Sausage and the Sequoia. These cataclysmic events restructured the Milky Way Galaxy, creating the thick disk, the stellar halo and the Splash.

We will discuss consequences of these results for the present-day distribution of dark matter, as well as their implications for ongoing direct & indirect dark matter detection experiments.
