Numerical multi-zone leptohadronic models of gamma rays and neutrino emission by magnetic reconnection
TeV gamma-ray emission has been detected from non-blazar low luminosity active galactic nuclei (LLAGN), establishing them as potential cosmic-ray accelerators as well as sources of PeV neutrino emission. However, current observations cannot determine whether the TeV gamma rays come from the jet or from the black hole (BH) core region. In this work we consider numerical general relativitic MHD models of advection-dominated accretion flows (ADAF) around BHs where turbulent magnetic reconnection is likely to occur and accelerate cosmic rays to high energies. We use this numerical ADAF model as a background environment where we perform Monte Carlo simulations of the propagation of cosmic rays employing the CRPropa3 code. In our models we consider the interaction of cosmic rays with the magnetic, matter, and photon fields of the ADAF and obtain gamma-ray and neutrino fluxes. Based on our results, we discuss whether the detected TeV emission from non-blazar LLAGNs originated in the BH core region.
