IceCube diffuse neutrino data constrains neutrino loss from new physics via energy conservation, yielding bounds that vary with attenuation energy dependence and source redshift assumptions while potentially affecting spectral index fits.
The Gluon Condensation model fits gamma-ray spectra of TXS 0506+056 and NGC 1068 with neutrino predictions consistent with IceCube, but predicts unphysical hardening for SNR G54.1+0.3.
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.
Memory-burden backreaction deforms the Hawking spectrum to suppress its high-energy tail, lowering total luminosity and neutrino flux by a factor set by a single suppression parameter and thereby relaxing IceCube bounds on primordial black hole dark matter.
