Description
We study the effects of interaction of jets in
Active Galactic Nuclei when they encounter stellar
clusters passing across the inner jet. The interaction provides a scenario to address
non–thermal processes. In jet–star interactions a double bow–shock
structure is formed where particles get accelerated via diffusive
mechanism. Individual encounters have a limited effect, however, dense
clusters of massive stars can truncate the jet as the cluster crosses the
jet line near the jet launching region. A bow shock is formed by the interaction of the cluster collective wind with the jet. Much of the jet kinetic energy
density is transferred to the shock and becomes available to accelerate
particles. The interaction of jets with clusters of
massive stars is a promising scenario to explain the gamma
ray emission from radiogalaxy jets.
