Title: | Diffuse Flux of Supernova Neutrinos |
Date (JST): | Wed, Jul 05, 2023, 15:30 - 17:00 |
Place: | Seminar Room A |
Abstract: |
The diffuse flux of supernova neutrinos provides an immediate opportunity to detect MeV neutrinos traveling over cosmological baselines. This signal is isotropic and constant in time, arising from the combined fluxes of neutrinos emitted from all distant stellar core collapses. It has not been detected yet, but with the Super-Kamiokande detector now upgraded with gadolinium, the first detection is anticipated in the next decade. In this talk, I will review predictions of this neutrino signal. Inputs from both the theoretical and observational communicates are crucial, and I will cover recent insights gained from both simulations of core collapse and surveys of supernovae and related observables. I will also cover various probes which will become possible in the discovery and precision phases of this upcoming flux of supernova neutrinos. |
