The recent detection of high-energy neutrinos from NGC 1068 supports the idea that AGN coronae—magnetized, compact regions around supermassive black holes—can accelerate protons and produce neutrinos via photohadronic interactions with X-ray photons. I present a plasma-informed framework for this coronal scenario, grounded in particle-in-cell simulations of magnetic reconnection and turbulence. Motivated by the NGC 1068 signal, I also examine whether similar coronal processes could contribute to neutrino production in blazars—AGN with a powerful jet pointing toward Earth. This is an exciting possibility in view of the neutrino association with a gamma-ray flare from the blazar TXS 0506+056. However, I show that a coronal origin is strongly disfavored in this case, reinforcing the interpretation of jet-based emission for blazars.
