An APOGEE-2 Survey of the Stellar Populations in the M31 Group

The Milky Way and Andromeda Galaxies present opportunities to study galaxy formation and evolution processes at a unique level of detail. We present initial results from a study of Andromeda group galaxies and globular clusters with high-resolution, integrated-light infrared spectroscopy from the SDSS-IV APOGEE-2 survey. We construct semi-empirical simple stellar population (SSP) spectra using APOGEE stellar templates and demonstrate their effectiveness in recovering fundamental parameters of composite stellar populations, including in M31 and some of its companion galaxies. The SSP library will be made publicly available for the community to use.
