Neutrinos from active galactic nuclei as a diagnostic tool

Abstract

Active galactic nuclei (AGN) are known as sources of high energy gamma-rays. The emission probably results from non-thermal radiation of relativistic jets belonging to the AGN. Earlier investigations of these processes have suggested that neutrinos are among the radiation products of the jets and may be used to discriminate between hadrons and leptons as primary particles for the production of the high energy emission. It is shown that the neutrino flux is correlated with the flux of TeV gamma-rays. This allows to distinctly search for neutrino emissions from the jets of AGN by using the TeV gamma-ray light curves to drastically reduce the temporal and spatial parameter space. Given the observed TeV photon fluxes from nearby BL Lacs the neutrino signal from AGN may be detectable with future neutrino observatories as least as sensitive as IceCube.
