Talk Title: “Relic Neutrino Physics with the South Pole Telescope”



During the Big Bang, neutrinos were produced in tremendous quantities and today compete with photons for the title of most numerous particle in the universe. Through gravitational interactions, this neutrino sea has had profound effects on the history of our universe. These effects depend on fundamental and hard-to-measure properties of neutrinos, notably neutrino mass, the mass hierarchy, and the existence of sterile neutrinos and other light, non-interacting particles. High-resolution surveys of the cosmic microwave background (CMB) can measure these effects, providing a unique window into neutrino physics and the properties of the dark sector, as well as probing a wide range of other physics. In this context, I will discuss the SPT-3G receiver for the South Pole Telescope, deployed at the beginning of this year, as well as the follow-on CMB-S4 project, which is expected to provide a high-significance detection of neutrino mass even at the minimum allowed by terrestrial oscillation measurements.
