Since their discovery over a century ago, the origin of cosmic rays of the highest energies is still widely uncertain. While in the past much attention was paid to analyzing steady state source models, bursting sources that appear in quiescent and flaring states, like the class of Active Galactic Nuclei (AGN) seem to be a promising candidate for possible sources of ultra-high-energy cosmic rays (UHECR). The goal of this work is trying to understand the detailed behaviour of bursting sources by simulating the time resolved propagation of a plasma blob inside the jet of an AGN. For this purpose, a tool for cosmic-ray propagation in relativistic plasmoids of AGN jets has been developed and implemented into the open-source code CRPropa 3.1. With this framework, we will predict the multimessenger signatures of flaring sources, aiming to contribute to a more complete picture of the UHECR sky including the bursting sources and therefore also to a deeper understanding of the origin of the highest energetic charged particles. First results of the flaring behaviour from relativistic plasmoids are being presented.
