The Supernova Early Warning System (SNEWS) is a cooperative effort between the world's neutrino detection experiments to spread the news that a star in our galaxy has just experienced a core-collapse event and is about to become a Type II Supernova. This project exploits the ~hours time difference between neutrinos promptly escaping the nascent supernova and photons which originate when the...
While the detection of a neutrino burst from a galactic supernova would provide a plethora of information on the stellar collapse as well as the neutrino properties, the low rate of 1-2 CCSNe per century make this a tedious endeavor. Instead, a detector with an effective mass of 10 Mton at 10MeV would detect extra-galactic supernovae at a rate of 1-2 per year - albeit with a much lower number...
We discuss the recent progress in our understanding of flavor evolution in dense astrophysical environments, in particular core-collapse supernovae and binary neutron star mergers. We highlight what we might learn from a galactic supernova, the connection to r-process nucleosynthesis and to the recent kilonova observation.
In this talk the status of both known and unknown neutrino oscillation parameters will be reviewed, with particular focus on the mass ordering and the its discrimination with present experiments and future projects. In this context our current understanding of supernova neutrino flavor conversions is discussed, from ordinary flavor oscillations during the shock-wave propagation to collective...
