Description
The IceCube Neutrino Observatory has reported evidence of TeV-scale neutrinos emitted from NGC 1068, a nearby Seyfert II galaxy. The evidence suggests that active galactic nuclei could be potential sources of high-energy astrophysical neutrinos. The absence of the expected accompanying flux of TeV gamma-rays indicates that they could have been efficiently obscured at their production site, where the hot coronal environment near the core of the Seyfert Galaxy naturally becomes a candidate. According to theoretical models, the property of the corona, and therefore the production of neutrinos, can be calculated by using the intrinsic X-ray luminosity. In this poster, we present our search for neutrino emission from a sample of intrinsic X-ray bright Seyfert Galaxies selected from the BASS survey. In our study, we employed a disc-corona model of the neutrino flux to improve the discovery potential of the search and compared it to using the standard power-law flux assumption.
