Clouds, Streams and Bridges. Redrawing the blueprint of the Magellanic System with Gaia DR1
Vasily Belokurov, Denis Erkal, Alis J. Deason +5
We present the discovery of stellar tidal tails around the Large and the Small Magellanic Clouds in the Gaia DR1 data. In between the Clouds, their tidal arms are stretched towards…
The Clouds are breaking: tracing the Magellanic system with Gaia DR1 Mira variables
Alis J. Deason, Vasily Belokurov, Denis Erkal +2
We exploit the first data release from the Gaia mission to identify candidate Mira variables in the outskirts of the Magellanic Clouds. The repeated observations of sources during…
Isotropic at the Break? 3D Kinematics of Milky Way Halo Stars in the Foreground of M31
Emily C. Cunningham, Alis J. Deason, Puragra Guhathakurta +6
We present the line-of-sight (LOS) velocities for 13 distant main sequence Milky Way halo stars with published proper motions. The proper motions were measured using long baseline…
The Eating Habits of Milky Way Mass Halos: Destroyed Dwarf Satellites and the Metallicity Distribution of Accreted Stars
Alis J. Deason, Yao-Yuan Mao, Risa H. Wechsler
We study the mass spectrum of destroyed dwarfs that contribute to the accreted stellar mass of Milky Way (MW) mass M_vir ~ 10^12.1 M_sun) halos using a suite of 45 zoom-in, dissipa…
