Hadronic modeling of AGN variability — •Matthias Weidinger¹ and Felix Spanier² — ¹Theoretische Physik IV, Ruhr-Universität Bochum — ²ITPA, Universität Würzburg

While synchrotron emission being responsible for the first peak in the typical double-humped spectral energy distribution of blazars is beyond question, the situation in the very high energy regime is still a matter of debate. Compton up-scattering of internal (jet) photons works well for many, but - by far - not for all blazars. Either external radiation fields or non-thermal protons within the jet need to be present to explain the broadband emission of e.g. flat spectrum radio quasars consistently. A time-dependent hybrid emission model is introduced here. With the available contemporaneous data increasing steadily the information extracted from short time variability can be used to distinguish between the different models, without relying neutrino detections. The principle is explained using the blazar 1ES1011+496.
