Non-thermal emission from the interaction of extragalactic jets with stars

Abstract

The central regions of galaxies are rich environments, with abundant stars and medium inhomogeneities. For galaxies hostingactive galactic nuclei, the interaction of a relativistic jet with obstacles can lead to the formation of shocks, where particles canbe accelerated up to relativistic energies. In this work, we analyze the non-thermal radiation produced by electrons accelerated inthese shocks. We first characterize the stellar population inside the jet. Then, we study the transport of relativistic electrons, andcompute their synchrotron and inverse Compton emission. In particular, we focus our research on AGN jets aligned with the lineof sight, where the observed emission is significantly enhanced by Doppler boosting.
