Simplified model for photohadronic interactions in cosmic accelerators — •Svenja Hümmer, Michael Rüger, Felix Spanier, and Walter Winter — Institut für Theoretische Physik und Astrophysik, Universität Würzburg, Germany

We present a fast analytical model for photomeson production in astrophysical sources like AGNs or GRBs which is suitable for time-dependent simulations of the sources and fit models for neutrino fluxes. It is built on basic physical principles and is simplified in such a way that secondary cooling can be included. We deal with π⁺ and π⁻ seperately in order to predict the neutrino to antineutrino ratios.
