Description
Active galactic nuclei (AGN), and the accompanied AGN jets, are some of
the most fascinating and luminous objects in the observable Universe.
Both the active cores and their jets are candidates for the engine of
cosmic rays, gamma rays, and neutrinos with the highest energies measured at Earth.
A deep understanding of the processes related to jets will not only
fuel the field of high energy cosmic rays, but will also give insights in
fundamental plasma, astro, and particle physics. The physical and
mathematical modeling of an AGN jet is challenging, with ambiguous
signatures that need to be understood by numerical simulations of
cosmic ray transport and interactions. Based on the work of Hoerbe et al.
(MNRAS 2020), a simulation framework for hadronic constituents and
their interactions inside of a plasmoid, propagating along the AGN jet
axis, was made. The final goal of the simulation is to give
predictions in the context of multimessenger astrophysics. This talk will present
the first results, discuss the question of diffusivity of the particles and examine the scenario, where neutrino and gamma-ray flares coincide.
