Talk Title: Turning a Dark Matter Detector into a Neutrino Observatory: Latest Results from XENONnT Abstract: XENONnT's exceptionally low background and low energy threshold have transformed a dark matter detector into a powerful observatory for solar neutrinos. I will present recent measurements of elastic neutrino-electron scattering and coherent elastic neutrino-nucleus scattering, which probe solar neutrinos through complementary electronic and nuclear recoil channels and open new opportunities for precision electroweak and neutrino physics.
