Correlated neutrino and gamma-ray emission from AGN — •Marlene Doert — TU Dortmund

The origin of very high energy gamma-rays from AGN is still subject to debates. In a hadronic production scenario an accompanied emission of neutrinos should take place. Thus, the detection of neutrinos from these sources would be the ultimate way to distinguish leptonic from hadronic production processes. In this presentation a bolometric approach for the prediction of the neutrino flux from AGN sources based on the measured flux in gamma-rays will be discussed. Subsequently its detectability by state-of-the-art neutrino experiments like the IceCube detector will be investigated for well-studied blazars. Paying attention to the fact that AGN are often highly variable sources, low state measurements as well as measurements taken during flaring activity are taken into account. The resulting predicted neutrino fluxes will be presented and the still open parameter space will be discussed. Finally, conclusions will be drawn in terms of an impact of this study on the currently debated production models.
