A population of AGN coronae with magnetization parameters spanning up to σ ~ 10 can reproduce the entire observed diffuse neutrino flux from TeV to PeV energies.
A proton spectrum with index -3.1 interacting with 0.3 keV X-rays via the Delta resonance reproduces the observed 30 TeV neutrino break and limits the accompanying gamma-ray cascade contribution to ~10% of the isotropic background at 3 GeV.
High-energy astrophysical neutrinos can constrain the running of neutrino mixing parameters with energy, with future multi-detector setups forecast to set strong bounds despite astrophysical uncertainties.
Calibrated AGN disk-wind models contribute ≲5% to the CGB above 10 GeV and ≲10% to the CNB at 100 TeV and are unlikely to dominate either background.
The diffuse astrophysical neutrino flux is interpreted as dominated by a single source class with dominant pγ production for target photon temperatures of 0.1-1 keV.
Phenomenological study predicting incomplete tau polarization at FASER2, observable neutrino and muon trident processes, and contributions to hadron structure from IceCube neutrino events.
