Abstract: We discuss the science motivations and prospects for a joint analysis ofgravitational-wave GW and low-energy neutrino data to search for promptsignals from nearby supernovae SNe. Both gravitational-wave and low-energyneutrinos are expected to be produced in the innermost region of acore-collapse supernova, and a search for coincident signals would probe theprocesses which power a supernova explosion. It is estimated that the currentgeneration of neutrino and gravitational-wave detectors would be sensitive toGalactic core-collapse supernovae, and would also be able to detectelectromagnetically dark SNe. A joint GW-neutrino search would enableimprovements to searches by way of lower detection thresholds, larger distancerange, better live-time coverage by a network of GW and neutrino detectors, andincreased significance of candidate detections. A close collaboration betweenthe GW and neutrino communities for such a search will thus go far towardrealizing a much sought-after astrophysics goal of detecting the next nearbysupernova.
