The Southern Stellar Stream Spectroscopic Survey (S5): Chemical Abundances of Seven Stellar Streams
Alexander P. Ji, Ting S. Li, Terese T. Hansen +16
We present high-resolution Magellan/MIKE spectroscopy of 42 red giant stars in seven stellar streams confirmed by the Southern Stellar Stream Spectroscopic Survey (S5): ATLAS, Aliq…
The tidal remnant of an unusually metal-poor globular cluster
Zhen Wan, Geraint F. Lewis, Ting S. Li +18
Globular clusters are some of the oldest bound stellar structures observed in the Universe. They are ubiquitous in large galaxies and are believed to trace intense star formation e…
The Pristine Inner Galaxy Survey (PIGS) II: Uncovering the most metal-poor populations in the inner Milky Way
Anke Arentsen, Else Starkenburg, Nicolas F. Martin +19
Metal-poor stars are important tools for tracing the early history of the Milky Way, and for learning about the first generations of stars. Simulations suggest that the oldest meta…
Broken into Pieces: ATLAS and Aliqa Uma as One Single Stream
Ting S. Li, Sergey E. Koposov, Denis Erkal +17
We present the first spectroscopic measurements of the ATLAS and Aliqa Uma streams from the Southern Stellar Stream Spectroscopic Survey (), in combination with the photometri…
