Hunting Supernova neutrinos with dark matter detectors

During a massive star’s death, 99% of its energy is released in the form of neutrinos. Neutrinos of all flavors escape the core well before any light. If detected, they can provide crucial information on stellar core collapse and its mechanisms. Detection of the next galactic supernova will provide the first multimessenger signal from electromagnetic waves, gravitational waves, and neutrinos. While existing neutrino observatories mostly probe neutrinos of a single flavor, ton-scale dark matter detectors can provide information from all flavors through coherent elastic neutrino-nucleus scattering, CEνNs, in the low-energy (few keV) range.

In this talk, we will discuss the challenges and opportunities of using two-phase xenon dark matter detectors for supernovae neutrino detection, and we will review some of the recent results and future prospects in this exciting field of research. I am also going to introduce the supernova early warning system, SNEWS, and the integration of the XENONnT experiment to SNEWS.
