The diffuse supernova neutrino background: an update with modern population synthesis and core collapse simulations

We provide the integrated diffuse supernova neutrino background, see arXiv:2506.22699 for the detail. The files correspond to the solid lines in fig. 6 of arXiv:2506.22699 , which is the case including binary effects and black hole forming collapses. Results are for un-oscillated neutrino fluxes (no flavor mixing) and are given for the BPASS case (file ..._BPASS.txt ) and the KIHNN case (file ..._KIHNN.txt). Data Format: The data are in ASCII format and the meaning of the columns are as follows. 1: neutrino energy [MeV] 2: electron-type neutrino flux [cm^-2 MeV^-1 s^-1] 3: anti-electron-type neutrino flux [cm^-2 MeV^-1 s^-1] 4: x-type neutrino flux [cm^-2 MeV^-1 s^-1]
