Hadronic modeling of TeV AGN: gammas and neutrinos

Abstract

Blazar emission models are usually divided into two big families, leptonic and hadronic, according to the particles which are responsible for the gamma-ray component of their spectral energy distributions. Even though leptonic models have been successful in explaining the gamma-ray emission from most blazars, hadronic models still present an intriguing alternative. They have the unique advantage to link the emission of photons, neutrinos, and cosmic rays from the astrophysical source. We have developed a stationary one-zone lepto-hadronic code to model the emission from blazars in both leptonic and hadronic scenarios. In this contribution we focus on hadronic modeling of a few selected TeV blazars of the BL Lac type and the radio galaxy Centaurus A detected by Cherenkov telescopes. We study in particular their associated neutrino emission, for different hadronic scenarios, and how it compares to the sensitivity of current neutrino detectors.
