SUMMARY:Katelin Schutz (UCB) - Excluding a thin dark matter disk in the Milky Way with Gaia DR1: Resurrecting the Dinosaurs
DESCRIPTION:If a component of the dark matter has dissipative interactions\, it could collapse to form a thin dark disk in our Galaxy coincident with the baryonic disk. It has been suggested that dark disks could explain a variety of observed phenomena\, including mass extinction events due to periodic comet impacts. Using the first data release from the Gaia space observatory\, I will present the results of a search for a dark disk via its effect on stellar kinematics in the Milky Way. I will discuss our strong new limits that disfavor the presence of a thin dark matter disk and present updated measurements on the total matter density in the solar neighborhood.
