Description
Jets of active galactic nuclei (AGN) rank among the most promising candidates for the sources of extragalactic high-energy neutrinos. In this presentation, I will begin by briefly building a broad picture of these jets first from recent observations, then by covering our current theoretical interpretations of their dynamics and multi-wavelength emissions, which will define a set of open questions. I will then turn to recent theoretical advances, ranging from analytical models to relativistic magnetohydrodynamic simulations of jets, which together shed light on some of these open questions. In particular, I will present a scenario in which the interaction of an AGN jet with red giant stars provides a site for particle acceleration and, potentially, high-energy neutrino production. I will close by discussing what these results imply for the future of multi-messenger astronomy.
