The diffuse supernova neutrino background, a new window to the Universe

Since the first generation of stars, core-collapse supernovae have produced a steady flux of neutrinos, which could be detectable in the next-generation of experiments. Measuring this continuous flux, known as the diffuse supernova neutrino background (DSNB), could put novel bounds on possible beyond-the-Standard Model scenarios, such as lifetimes and oscillations expected if neutrinos are pseudo-Dirac particles. Moreover, the DNSB could teach us about cosmology and astrophysics since these neutrinos have been propagating in an expanding Universe, for instance.  We will explore these possibilities in this talk.
