Evidence of Neutrino Emission from X-ray Bright Seyfert Galaxies with IceCube

The IceCube Neutrino Observatory is a cubic-kilometer detector at the South Pole deep in the Antarctic ice that identifies high-energy neutrinos by detecting Cherenkov radiation. Following IceCube’s detection of TeV neutrinos from NGC 1068, more X-ray bright Seyfert galaxies have been selected based on their intrinsic X-ray luminosities and investigated using IceCube data. In this study, a coronal model where cosmic-ray acceleration and hadronic interactions occur near the AGN engine has been employed, linking X-ray and neutrino luminosities, providing physically motivated spectral shapes and stacking weights to enhance discovery potential. In this talk, I will present the outcomes of the studies on X-ray bright Seyfert galaxies and compare the results of using the coronal model with generic power-law assumptions.
