Newly Discovered Wolf–Rayet Stars in M31
The Astronomical Journal, 2023 The evolved massive star populations of the Local Group galaxies are generally thought to be well understood. However, recent work has suggested that the Wolf–Rayet (WR) content of M31 may have been underestimated.

Evidence for a Massive Andromeda Galaxy Using Satellite Galaxy Proper Motions
The Astrophysical Journal, 2023 We present new mass estimates for Andromeda (M31) using the orbital angular momenta of four satellite galaxies (M33, NGC 185, NGC 147, and IC 10) derived from existing proper motions, distances, and line-of-sight velocities. We infer two masses for M31: $

The Chemodynamics of the Stellar Populations in M31 from APOGEE Integrated-light Spectroscopy
The Astrophysical Journal, 2023 We present an analysis of nearly 1000 near-infrared, integrated-light spectra from APOGEE in the inner ∼7 kpc of M31. We utilize full-spectrum fitting with A-LIST simple stellar population spectral templates that represent a population of stars with the ...

Searching for Radio Outflows from M31* with VLBI Observations
The Astrophysical Journal, 2023 As one of the nearest and most dormant supermassive black holes (SMBHs), M31* provides a rare but promising opportunity for studying the physics of black hole accretion and feedback at the quiescent state. Previous Karl G.
