Elemental Abundances in M31: The Kinematics and Chemical Evolution of Dwarf Spheroidal Satellite Galaxies
Evan N. Kirby, Karoline M. Gilbert, Ivanna Escala +4
We present deep spectroscopy from Keck/DEIMOS of Andromeda I, III, V, VII, and X, all of which are dwarf spheroidal satellites of M31. The sample includes 256 spectroscopic members…
Evolution of the Stellar Mass-Metallicity Relation. II. Constraints on Galactic Outflows from the Mg Abundances of Quiescent Galaxies
Nicha Leethochawalit, Evan N. Kirby, Richard S. Ellis +2
We present the stellar mass-[Fe/H] and mass-[Mg/H] relation of quiescent galaxies in two galaxy clusters at and . We derive the age, [Fe/H], and [Mg/Fe] for…
Tentative Detection of the Circumgalactic Medium of the Isolated Low-Mass Dwarf Galaxy WLM
Y. Zheng, M. E. Putman, A. Emerick +7
We report a tentative detection of the circumgalactic medium (CGM) of WLM, an isolated, low-mass (log), dwarf irregular galaxy in the Local Group (LG). We an…
Elemental Abundances in M31: A Comparative Analysis of Iron and Alpha Element Abundances in the Outer Disk, Giant Stellar Stream, and Inner Halo of M31
Ivanna Escala, Karoline M. Gilbert, Evan N. Kirby +3
We measured [Fe/H] and [/Fe] using spectral synthesis of low-resolution stellar spectroscopy for 70 individual red giant branch stars across four fields spanning the outer disk,…
Elemental Abundances in M31: First Alpha and Iron Abundance Measurements in M31's Giant Stellar Stream
Karoline M. Gilbert, Evan N. Kirby, Ivanna Escala +3
We present the first measurements of [Fe/H] and [/Fe] abundances, obtained using spectral synthesis modeling, for red giant branch stars in M31's giant stellar stream. The spect…
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…
