Study of the transport behaviour in blazars under the influence of hadronic and photohadronic interactions * — •Vladimir Kiselev1,2, Marcel Schroller1,2, Julia Becker Tjus1,2, and Patrick Reichherzer1,2 — 1Theoretische Physik IV, Ruhr-Universität Bochum — 2RAPP Center, Ruhr-Universität Bochum
Active Galactic Nuclei (AGN) are considered among the few possible sources of high-energy neutrino emission. Therefore, it is important to describe the temporal behaviour and their signal correctly in the multimessenger picture. The most commonly used approach to describe a blazar flare in the present work has been applied, where a population of high-energy primary protons enters a plasmoid, travelling along the jet axis. One such realisation is the modified version of the publicly available propagation framework CRPropa 3.2, which modular structure offers two different propagation approaches, i.e. the equation of motion (EoM) and the solution of the transport equation, under consideration of a broad network of interactions. Previously, it has been shown how, in the considered high-energy range of primary protons, a transition between ballistic and diffusive behaviour takes place, which influences the spectral energy distribution, as well as the light curve of flares. The present work is an extension of the aforementioned work, where the same energy range is considered. In this talk we investigate how the introduction of hadronic interaction modules influences the diffusive behaviour of protons and the transition between both propagation regimes. * Supported by DFG (SFB 1491).
