Title: Fundamental Physics of Dark Matter from Dwarf Galaxy Surveys

Abstract: Dwarf galaxies, which are abundant in number and rich in their dark components, serve as an excellent probe of dark matter. By combining simulations, galaxy-halo connection models, and dwarf galaxy surveys, we can jointly constrain galaxy formation and dark matter physics. I will show recent results from the SAGA Survey, a spectroscopic survey that searches for satellite dwarf galaxies in nearby Milky Way-like systems, and demonstrate how these results put our own Milky Way in a cosmological context and provide insights into the coevolution of galaxies and dark matter halos. I will then discuss how the technique and data from the SAGA Survey can be applied to ongoing and upcoming surveys, in particular Rubin LSST, to enable us to identify a much larger population of dwarf galaxies in coming years to reveal the fundamental physics of dark matter.
