Description

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, we investigate more X-ray bright Seyfert galaxies, selected based on their intrinsic X-ray luminosities, using IceCube data. We utilize a coronal model where cosmic-ray acceleration and hadronic interactions occur near the AGN engine. This model links X-ray and neutrino luminosities, providing physically motivated spectral shapes and stacking weights to enhance discovery potential. In this poster, we present the outcomes of our studies on X-ray bright Seyfert galaxies. Finally, we compare our results of using the coronal model with generic power-law assumptions.
