Asymmetric Drift in the Andromeda Galaxy (M31) as a Function of Stellar Age
Amanda C. N. Quirk, Puragra Guhathakurta, Laurent Chemin +5
We analyze the kinematics of Andromeda's disk as a function of stellar age by using photometry from the Panchromatic Hubble Andromeda Treasury (PHAT) survey and spectroscopy from t…
Elemental Abundances in M31: Alpha and Iron Element Abundances from Low-Resolution Resolved Stellar Spectroscopy in the Stellar Halo
Ivanna Escala, Evan N. Kirby, Karoline M. Gilbert +2
Measurements of [Fe/H] and [/Fe] can probe the minor merging history of a galaxy, providing a direct way to test the hierarchical assembly paradigm. While measurements of [/F…
Project AMIGA: Distance and Metallicity Gradients Along Andromeda's Giant Southern Stream from the Red Clump
Roger E. Cohen, Jason S. Kalirai, Karoline M. Gilbert +7
The Giant Southern Stream (GSS) of M31, a keystone signature of a major accretion event, yields crucial constraints on M31 formation and evolution models. Currently, our understand…
Constraints for the Progenitor Masses of Historic Core-Collapse Supernovae
Benjamin F. Williams, Tristan J. Hillis, Jeremiah W. Murphy +3
We age-date the stellar populations associated with 12 historic nearby core-collapse supernovae (CCSNe) and 2 supernova impostors, and from these ages, we infer their initial masse…
