: New insights from deep spectroscopic observations of the tidal tails of the globular clusters NGC 1261 and NGC 1904
Petra Awad, Ting S. Li, Denis Erkal +22
As globular clusters (GCs) orbit the Milky Way, their stars are tidally stripped forming tidal tails that follow the orbit of the clusters around the Galaxy. The morphology of thes…
Chemical Abundances in the Leiptr Stellar Stream: A Disrupted Ultra-faint Dwarf Galaxy?
Kaia R. Atzberger, Sam A. Usman, Alexander P. Ji +11
Chemical abundances of stellar streams can be used to determine the nature of a stream's progenitor. Here we study the progenitor of the recently discovered Leiptr stellar stream,…
Inferring dark matter subhalo properties from simulated subhalo-stream encounters
Tariq Hilmi, Denis Erkal, Sergey E. Koposov +9
In the cold dark matter paradigm, our Galaxy is predicted to contain >10000 dark matter subhaloes in the range which should be completely devoid of stars. Stella…
Spectacular nucleosynthesis from early massive stars
Alexander P. Ji, Sanjana Curtis, Nicholas Storm +39
Stars formed with initial mass over 50 Msun are very rare today, but they are thought to be more common in the early universe. The fates of those early, metal-poor, massive stars a…
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…
