TeV Neutrinos and Hard X-Rays from Relativistic Reconnection in the Corona of NGC 1068
Published 2024-01-01“…Protons above the break lose most of their energy within the reconnection layer via photohadronic collisions with the coronal X-rays, producing a neutrino signal in good agreement with the recent observations. Gamma rays injected in photohadronic collisions are cascaded to lower energies, sustaining the population of electron–positron pairs that makes the corona moderately Compton thick.…”
