The Metallicity Distribution of the Ultra-Faint Dwarf Galaxy Segue 1
Daisy Bissonette, Alexander P. Ji, Joshua D. Simon +6
Ultra-faint dwarf galaxies (UFDs; stellar masses ) offer unique insights into early chemical evolution in low-mass systems. However, interpreting their metalli…
No Observational Evidence for Dark Matter Nor a Large Metallicity Spread in the Extreme Milky Way Satellite Ursa Major III / UNIONS 1
William Cerny, Daisy Bissonette, Alexander P. Ji +9
The extremely-low-luminosity, compact Milky Way satellite Ursa Major III / UNIONS 1 (UMaIII/U1; ; pc) was found to have a substantial velocity d…
A Bimodal Metallicity Distribution Function in the Ultra-Faint Dwarf Galaxy Reticulum II
Alice M. Luna, Alexander P. Ji, Anirudh Chiti +6
Star formation in ultra-faint dwarf galaxies (UFDs, ) is suppressed by reionization, but may not be completely quenched. The metallicity distribution function (MD…
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,…
