Leptonic Model for Neutrino Emission from Active Galactic Nuclei
Leptonic Model for Neutrino Emission from Active Galactic Nuclei
It is often stated that the observation of high-energy neutrinos from an astrophysical source would constitute indisputable proof for the acceleration of hadronic cosmic rays. Here, we point out that there exists a purely leptonic mechanism to produce TeV-scale neutrinos in astrophysical environments. In particular, very high-energy synchrotron photons can …
