Cosmic rays, gamma-rays, and neutrinos from AGN winds

Galaxy scale outflows driven by active galactic nuclei (AGN) are likely to play a key role in the evolution of galaxies. In fact, they can perturb and possibly expel most of the gas out of the galaxy, offering a plausible physical origin for the close connection between the properties of black holes and their host galaxies. AGN-driven outflows can also induce shocks in the interstellar medium, which, in turn, can accelerate relativistic particles.
I will present a study of the non-thermal emissions produced by relativistic particles accelerated by the AGN-driven shocks in NGC 1068. NGC 1068 is a nearby prototypical Seyfert 2 galaxy which shows both starburst and nuclear activities in its central region. NGC 1068 is a strong gamma-ray emitter. It is the brightest of the few non-blazar galaxies detected by the Fermi gamma-ray space telescope.
I will show the gamma-ray and radio spectra predicted by the AGN outflow model, and I will discuss how these results compare with those corresponding to other commonly assumed sources of gamma-ray and radio emissions, like Supernova remnants or AGN jets.
I will compare the neutrino flux expected in the AGN outflow model with constraints from current experiments, and I will provide predictions for the detections by the upcoming KM3NeT neutrino telescope.
