Description

Since their discovery over a century ago, the origin of cosmic rays of the highest energies is still widely uncertain. A promising class of potential sources are Active Galactic Nuclei (AGN), that appear in quiescent and flaring states. To numerically modelate their local-source behaviour in detail, in foregoing work the software CRPropa was extended, to be able to capture the jet-physics on local scales, propagating a relativistic plasma blob along a jet axis. The goal of this work is trying to further extend this model accounting for a temporal variability of the source. For this purpose, a new source feature was introduced, allowing for a time dependent particle injection and therefore the finite lifetime of sources. Using a Monte-Carlo-Sampling approach, different luminosity profiles can be realized. In a next step, it is planned trying to modelate with this framework the multimessenger signatures of flaring AGN sources.
