The Red Supergiant Content of M31 and M33

We identify red supergiants (RSGs) in our spiral neighbors M31 and M33 using near-IR (NIR) photometry complete to a luminosity limit of . Our archival survey data cover 5 deg 2 of M31, and 3 deg 2 for M33, and are likely spatially complete for these massive stars. Gaia is used to remove foreground s...
