High-energy neutrinos from active galactic nuclei
Abstract
The paper examines the neutrino mechanism for the emission of cosmic rays from active galactic nuclei and the accompanying neutrino radiation. It is pointed out that the most promising sources here are massive black holes in active nuclei, where acceleration to very high energies is possible. A promising source is the Seyfert galaxy NGC 4151, which may be the source of ultrahigh-energy cosmic rays in the Local Supercluster. Sources of this type could produce a significant diffusive neutrino drift with E(n) greater than about 10 to the 6th GeV. The role of black holes as hidden sources in high-energy neutrino astronomy is discussed.
