Using Gaia DR2 to Constrain Local Dark Matter Density and Thin Dark Disk

Jatan Buch, John Shing Chau Leung, JiJi Fan

We use stellar kinematics from the latest Gaia data release (DR2) to measure the local dark matter density ${\rho }_{\mathrm{DM}}$ in a heliocentric cylinder of radius $R=150\mathrm{pc}$ and…
