The Diffuse Supernova Neutrino Background: Theoretical predictions, astronomical observations, and JUNO perspectives. The diffuse supernova neutrino background (DSNB) is a cosmic sea of relic MeV neutrinos and antineutrinos from all past stellar core-collapse (CC) events that produce successful or failed supernova (SN) explosions with either neutron-star (NS) or black-hole (BH) remnants. As part of this project, the DSNB will be measured using data from the JUNO detector. Additionally, a determination of the CCSN rate up to redshift z ∼ 1.5 is targeted by using data from the new wide-field Vera Rubin Observatory and gravitational lensing. Furthermore, the aim is to infer the otherwise inaccessible rate of BH forming CC events that do not produce visible SNe.
