Surveying Nearby Galaxies with Roman
I will discuss how the Nearby Galaxies Science Investigation Team (WINGS) is working to optimize the impact of the Roman Space Telescope on the study of nearby galaxies. Roman will be capable of mapping galaxy halo structures down to extremely faint surface brightness limits using individual stars. The resulting maps of stellar halos and accreting dwarf companions will provide stringent tests of galaxy formation and dark matter models on galactic (and even sub-galactic) scales.
