Abstract:
'Neutrino-emitting blazars may accelerate cosmic ray (CR) protons at the inner regions of the jet, where most of the magnetic energy is likely to be dissipated. In this picture, the spectrum of neutrinos and gamma-rays that leave the source is shaped by the soft photon fields that the parent hadrons encounter before leaving the source. We build a lepto-hadronic emission model based on particle acceleration by magnetic reconnection. The emission is powered by magnetic dissipation in the jet, in the transition from magnetically to kinetically dominated flow. We employ the striped jet model to obtain the jet properties at three characteristic emission regions and derive the associated electromagnetic and neutrino output. We also perform Monte Carlo simulations of the propagation CR protons as an alternative method for calculating the neutrino flux. We apply this emission model to interpret the 2017 multi-messenger event from the blazar TXS0506+056 and we also discuss applications of the model in the context of flat-spectrum radio quasars and BL Lac objects.'
