Linking hard X-ray and high-energy neutrino emission from radio-loud and radio-quiet AGN

Abstract: High-energy neutrinos, detected by the IceCube Neutrino Observatory, have been linked to both radio-loud and radio-quiet active galactic nuclei (AGN). While jets are often invoked to explain neutrino production in radio-loud AGN, we explore an alternative scenario based on observations: particle production in the gamma-obscured cores near supermassive black holes. We report comparable unabsorbed hard X-ray and neutrino luminosities in six AGNs, including the radio-quiet Seyfert galaxy NGC 1068 and the radio-loud blazar TXS 0506+056. Our findings point to a possible common origin of neutrino emission in diverse AGN classes.
