Neutrinos and ultra-high-energy nuclei from blazars: from a single-source model to a population study
Original language description
Five years after the discovery of the diffuse astrophysical neutrino flux, its origin is still unclear. At the same time, composition measurements of ultra-high-energy cosmic rays (UHECRs) seem to indicate a component heavier than protons. In this talk we present an interaction model of protons and heavier nuclei in blazar jets. In bright blazars, photo-nuclear interactions lead to extensive nuclear cascades of lighter elements, and we calculate numerically for the first time their effect on blazar neutrino emission. In the case of flat-spectrum radio quasars (FSRQs), our model considers the effect of CR propagation in the broadline region, which boosts neutrino production in these sources.
