Satellites of LMC-mass dwarfs: close friendships ruined by Milky Way mass haloes (2015)
Journal Article
Deason, A., Wetzel, A., Garrison-Kimmel, S., & Belokurov, V. (2015). Satellites of LMC-mass dwarfs: close friendships ruined by Milky Way mass haloes. Monthly Notices of the Royal Astronomical Society, 453(4), 3568-3574. https://doi.org/10.1093/mnras/stv1939

Motivated by the recent discovery of several dwarfs near the Large Magellanic Cloud (LMC), we study the accretion of massive satellites onto Milky Way (MW)/M31-like haloes using the ELVIS suite of N-body simulations. We identify 25 surviving LMC-mass... Read More about Satellites of LMC-mass dwarfs: close friendships ruined by Milky Way mass haloes.

Satellite Dwarf Galaxies in a Hierarchical Universe: Infall Histories, Group Preprocessing, and Reionization (2015)
Journal Article
Wetzel, A., Deason, A., & Garrison-Kimmel, S. (2015). Satellite Dwarf Galaxies in a Hierarchical Universe: Infall Histories, Group Preprocessing, and Reionization. Astrophysical Journal, 807(1), Article 49. https://doi.org/10.1088/0004-637x/807/1/49

In the Local Group (LG), almost all satellite dwarf galaxies that are within the virial radius of the Milky Way (MW) and Andromeda (M31) exhibit strong environmental influence. The orbital histories of these satellites provide the key to understandin...

The progenitors of the Milky Way stellar halo: big bricks favoured over little bricks (2015)
Journal Article
Deason, A., Belokurov, V., & Weisz, D. (2015). The progenitors of the Milky Way stellar halo: big bricks favoured over little bricks. Monthly Notices of the Royal Astronomical Society: Letters, 448(1), L77-L81. https://doi.org/10.1093/mnrasl/slv001

We present a census of blue horizontal branch (BHB) and blue straggler (BS) stars belonging to dwarf galaxies and globular clusters, and compare these counts to that of the Milky Way stellar halo. We find, in agreement with earlier studies, that the... Read More about The progenitors of the Milky Way stellar halo: big bricks favoured over little bricks.
