Clouds, Streams and Bridges. Redrawing the blueprint of the Magellanic System with Gaia DR1 (2016)
Journal Article
Belokurov, V., Erkal, D., Deason, A., Koposov, S., De Angeli, F., Wyn Evans, D., …Mackey, D. (2016). Clouds, Streams and Bridges. Redrawing the blueprint of the Magellanic System with Gaia DR1. Monthly Notices of the Royal Astronomical Society, 466(4), 4711-4730. https://doi.org/10.1093/mnras/stw3357

We present the discovery of stellar tidal tails around the Large and the Small Magellanic Clouds (LMC and SMC, respectively) in the Gaia DR1 data. In between the Clouds, their tidal arms are stretched towards each other to form an almost continuous s... Read More about Clouds, Streams and Bridges.

The Eating Habits of Milky Way-mass Halos: Destroyed Dwarf Satellites and the Metallicity Distribution of Accreted Stars (2016)
Journal Article
Deason, A., Mao, Y., & Wechsler, R. (2016). The Eating Habits of Milky Way-mass Halos: Destroyed Dwarf Satellites and the Metallicity Distribution of Accreted Stars. Astrophysical Journal, 821(1), Article 5. https://doi.org/10.3847/0004-637x/821/1/5

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, dissipationless simulations. Empirical models are employed to relate (peak) s... Read More about The Eating Habits of Milky Way-mass Halos: Destroyed Dwarf Satellites and the Metallicity Distribution of Accreted Stars.

Isotropic at the Break? 3D Kinematics of Milky Way Halo Stars in the Foreground of M31 (2016)
Journal Article
Cunningham, E., Deason, A., Guhathakurta, P., Rockosi, C., van der Marel, R., Toloba, E., …Dorman, C. (2016). Isotropic at the Break? 3D Kinematics of Milky Way Halo Stars in the Foreground of M31. Astrophysical Journal, 820(1), Article 18. https://doi.org/10.3847/0004-637x/820/1/18

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 (5-7 years) multi-epoch HST/ACS photometry, and the LOS velocities wer...
