The Milky Way's Shell Structure Reveals the Time of a Radial Collision
Thomas Donlon, Heidi Jo Newberg, Robyn Sanderson +1
We identify shell structures in the Milky Way for the first time. We find 2 shells in the Virgo Overdensity (VOD) region and 2 shells in the Hercules Aquila Cloud (HAC) region usin…
The Virgo Overdensity Explained
Thomas Donlon, Heidi Jo Newberg, Jake Weiss +2
We suggest that the Virgo Overdensity (VOD) of stars in the stellar halo is the result of a radial dwarf galaxy merger that we call the Virgo Radial Merger. Because the dwarf galax…
The substructures in the local stellar halo from Gaia and LAMOST
Hefan Li, Cuihua Du, Shuai Liu +2
Based on the second Gaia data release (Gaia DR2) and spectroscopy from the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) Data, we identified 20,089 halo stars…
The high velocity stars in the Local Stellar Halo from Gaia and LAMOST
Cuihua Du, Hefan Li, Shuai Liu +2
Based on the first Gaia data release and spectroscopy from the LAMOST Data Release 4, we study the kinematics and chemistry of the local halo stars. The halo stars are identified k…
