Neutrinos from blazars
Abstract
Gamma-ray evidence for nonthermal particles and intense photon fields in blazar AGNs make them a promising candidate for the production of1012 -1018 eV neutrinos. If nonthermal protons are injected with the same power as nonthermal electrons, then km3 -scale neutrino telescopes, such as IceCube, should detect high-energy neutrinos from blazars such as 3C 279. By contrast, BL Lac objects will be weaker neutrino sources due to the lack of intense external radiation fields near the blazar inner jets. High-energy neutron and photon beams produced in flat spectrum sources could power the extended jets and account for morphological difference between FR I and FR II radio galaxies. Neutrino telescopes could also detect jet sources hidden by Thomson-thick material.
