NGC 147 Corroborates the Break in the Stellar Mass-Stellar Metallicity Relation for Galaxies
Zhuyun Zhuang, Evan N. Kirby, Nicha Leethochawalit +1
The stellar mass-stellar metallicity relation (MZR) is an essential approach to probe the chemical evolution of galaxies. It reflects the balance between galactic feedback and grav…

Manganese Indicates a Transition from Sub- to Near-Chandrasekhar Type Ia Supernovae in Dwarf Galaxies
Mithi A. C. de los Reyes, Evan N. Kirby, Ivo R. Seitenzahl +1
Manganese (Mn) abundances are sensitive probes of the progenitors of Type Ia supernovae (SNe). In this work, we present a catalog of manganese abundances in dwarf spheroidal satell…

Evidence for Sub-Chandrasekhar Type Ia Supernovae from Stellar Abundances in Dwarf Galaxies
Evan N. Kirby, Justin L. Xie, Rachel Guo +6
There is no consensus on the progenitors of Type Ia supernovae (SNe Ia) despite their importance for cosmology and chemical evolution. We address this question by using our previou…
