Kinematics of Antlia 2 and Crater 2 from The Southern Stellar Stream Spectroscopic Survey (S5)
Alexander P. Ji, Sergey E. Koposov, Ting S. Li +15
We present new spectroscopic observations of the diffuse Milky Way satellite galaxies Antlia 2 and Crater 2, taken as part of the Southern Stellar Stream Spectroscopic Survey (S5).…
: The destruction of a bright dwarf galaxy as revealed by the chemistry of the Indus stellar stream
T. T. Hansen, A. P. Ji, G. S. Da Costa +13
The recently discovered Indus stellar stream exhibits a diverse chemical signature compared to what is found for most other streams due to the abundances of two outlier stars, Indu…
R-process-rich stellar streams in the Milky Way
Maude Gull, Anna Frebel, Karina Hinojosa +3
We present high-resolution Magellan/MIKE spectra of 22 bright () metal-poor stars ($-3.18<\mbox{[Fe/H]}<-1.37$) in three different stellar streams, the Helmi debris strea…
VLT Spectroscopy of Ultra-Faint Dwarf Galaxies. 1. Boötes I, Leo IV, Leo V
Sydney Jenkins, Ting S. Li, Andrew B. Pace +3
We perform consistent reductions and measurements for three ultra-faint dwarf galaxies (UFDs): Boötes I, Leo IV and Leo V. Using the public archival data from the GIRAFFE spectrogr…
