Description
The IceCube Neutrino Observatory has detected neutrino emission from the active galactic nuclei (AGNs) NGC 1068 and TXS 0506+056. While there has been a general consensus regarding the neutrino emission region in Seyfert galaxy NGC 1068, there has been an ongoing debate regarding the neutrino emission region in the blazar TXS 0506+056. This presentation aims to address this debate by arguing that the IceCube-detected neutrinos from TXS 0506+056 originate in the active galaxy's core, rather than the blazar jet. By comparing the neutrino emission mechanisms of TXS 0506+056 with the Seyfert galaxies NGC 1068 and NGC 4151, we demonstrate that an Eddington luminosity cosmic ray flux can consistently explain the neutrino emission in these systems.
