Description

The blazar TXS 0506+056 is a candidate of high-energy neutrino sources. We propose that its neutrino emission could originate from the core region rather than the jet. We suggests that high-energy protons, accelerated by magnetic reconnection within a magnetically arrested disk (MAD) near the central black hole, interact with photons from the accretion disk and corona to produce neutrinos.
