Boötes III is a Tidally Disrupting Ultra-Faint Dwarf Galaxy on an Eccentric Polar Orbit
Ting S. Li, Denis Erkal, Andrew B. Pace +20
We present updated systemic properties of the ultra-faint dwarf galaxy Boötes III from the Southern Stellar Stream Spectroscopic Survey (S). We identify 21 high-probability me…
The VMC survey -- LV. The coherent expansion of the SMC
S. Vijayasree, F. Niederhofer, M. -R. L. Cioni +8
The Small Magellanic Cloud (SMC) exhibits significant kinematic disequilibrium due to interactions with the Large Magellanic Cloud (LMC). Here, we investigate the two-dimensional s…
Sifting for a Stream: The Morphology of the Stellar Stream
Benjamin Cohen, Alexander P. Ji, Peter S. Ferguson +18
Stellar streams are sensitive laboratories for understanding the small-scale structure in our Galaxy's gravitational field. Here, we analyze the morphology of the stellar st…
Epicyclic Density Variations in the Indus Stellar Stream
Yong Yang, Geraint F. Lewis, Ting S. Li +12
Longitudinal density fluctuations observed in stellar streams can result from gravitational interactions with massive perturbers in the Milky Way, such as dark matter subhalos. Ana…
Overview of The SDSS-V Magellanic Genesis Survey
David L. Nidever, Danny Horta, Steven R. Majewski +14
The Sloan Digital Sky Survey-V (SDSS-V) Magellanic Genesis survey is a spectroscopic program designed to map the kinematic and chemical structure of the Magellanic Clouds using APO…
Multiple Populations and a CH Star Found in the 300S Globular Cluster Stellar Stream
Sam A. Usman, Alexander P. Ji, Ting S. Li +14
Milky Way globular clusters (GCs) display chemical enrichment in a phenomenon called multiple stellar populations (MSPs). While the enrichment mechanism is not fully understood, th…
