Elevated r-process enrichment in Gaia Sausage and Sequoia
David S. Aguado, Vasily Belokurov, G. C. Myeong +6
The Gaia Sausage (GS) and the Sequoia represent the major accretion events that formed the stellar halo of the Milky Way. A detailed chemical study of these main building blocks pr…
Orbital Clustering Identifies the Origins of Galactic Stellar Streams
Ana Bonaca, Rohan P. Naidu, Charlie Conroy +9
The origins of most stellar streams in the Milky Way are unknown. With improved proper motions provided by Gaia EDR3, we show that the orbits of 23 Galactic stellar streams are hig…
The S2 Stream: the shreds of a primitive dwarf galaxy
David S. Aguado, G. C. Myeong, Vasily Belokurov +12
The S2 stream is a kinematically cold stream that is plunging downwards through the Galactic disc. It may be part of a hotter and more diffuse structure called the Helmi stream. We…
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…
