Dynamical Relics of the Ancient Galactic Halo
Zhen Yuan, G. C. Myeong, Timothy C. Beers +11
We search for dynamical substructures in the LAMOST DR3 very metal-poor (VMP) star catalog. After cross-matching with Gaia DR2, there are 3300 VMP stars with available high-quality…
Dark Shards: velocity substructure from Gaia and direct searches for dark matter
Ciaran A. J. O'Hare, N. Wyn Evans, Christopher McCabe +2
Data from the Gaia satellite show that the solar neighbourhood of the Milky Way's stellar halo is imprinted with substructure from several accretion events. Evidence of these event…
Evidence for Two Early Accretion Events That Built the Milky Way Stellar Halo
G. C. Myeong, E. Vasiliev, G. Iorio +2
The Gaia Sausage is the major accretion event that built the stellar halo of the Milky Way galaxy. Here, we provide dynamical and chemical evidence for a second substantial accreti…
