Description
Recent IceCube observations reveal a significant excess of TeV neutrinos from the Seyfert II galaxy NGC 1068, marking the first robust association of astrophysical neutrinos with a non-jetted AGN despite the absence of gamma-ray emission. The remarkable X-ray brightness of this source suggests that dense X-ray photon fields near the supermassive black hole may act simultaneously as targets for neutrino-producing interactions and as efficient gamma-ray absorbers. The latest IceCube population studies are starting to show a correlation between neutrinos and X-ray bright AGN. Together, these results point to obscured, non-jetted AGN as the first emerging population of extragalactic neutrino sources.
