SUMMARY:Cosmic rays\, gamma-rays\, and neutrinos from AGN winds
DESCRIPTION: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.\nI 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.\nI 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.\nI 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.
