High-energy neutrinos from AGN — •Marius Toschke1,2, Julia Becker Tjus1, and Wolfgang Rhode2 — 1Ruhr-Universität Bochum — 2TU Dortmund
In the outer space there are galactic and extragalactic sources like gamma-ray bursts (GRB), active galactic nuclei (AGN), supernovae or other phenomena which produce high-energy neutrinos. In contrast to supernovae, GRBs and AGN are supposed to generate neutrinos at the highest energies. Neutrinos have a tiny cross section as they mainly suffer from the weak interaction. Therefore, they are useful messenger particles providing information about the direction of the source. With observations of the gamma flux from galactic and extragalactic sources, it is possible to make predictions for the neutrino flux. We suppose that neutrinos are predominantly generated by inelastic proton-proton interactions and derive the possible galactic and extragalactic sources. In this talk, first results are presented.
