Leptonic originated high-energy neutrinos from astrophysical objects

Abstract High-energy neutrinos are frequently regarded as signatures of hadronic cosmic rays in astrophysical environments. In this work, our modeling suggests that TeV neutrinos could potentially be produced by energetic electrons through electromagnetic processes in certain cosmic-ray accelerators. Under specific parameter spaces, the resulting fluxes appear comparable to those expected from hadronic interactions, indicating that electrons may contribute to the neutrino signals detected by the IceCube Observatory. These findings suggest a potential expansion of the conventional interpretation of neutrino origins and highlight the utility of joint gamma-ray and neutrino observations to help discriminate between hadronic and leptonic production mechanisms.
