摘要：
The detection of ultra high energy cosmic rays with E > 10(19) eV implies the existence of high energy neutrinos, originating from extragalactic sources. Neutrinos are suitable messenger particles, pointing back to the origin of cosmic rays when produced in local interactions. Extragalactic neutrino sources are among others gamma-ray bursts (GRBs) and active galactic nuclei (AGN), where protons are accelerated to high energies, collide and produce secondaries, which decay among others in neutrinos. Here, the focus will be on proton proton interactions in AGN. First results for the target densities n(H), for FR-I galaxies will be presented.
