Search for neutrino emission from southern sky Seyfert galaxies using IceCube datasets

ORAL

Abstract

The IceCube Neutrino Observatory, situated at the Amundsen-Scott South Pole Station, has made significant contributions in the fields of particle physics and astrophysics. IceCube reported the evidence of TeV neutrinos from the nearby Seyfert II galaxy source NGC 1068 at 4.2σ significance. The absence of corresponding TeV gamma-ray flux in this observation suggests that neutrinos are produced in a region that is opaque to gamma rays, and a probable location is the hot corona near the supermassive black hole (SMBH) at the AGN core. In this research, we conduct a follow-up analysis on the 14 X-ray bright Seyfert galaxies in the southern sky from the BAT AGN Spectroscopic Survey (BASS) catalog using a combined dataset. The two datasets used in this analysis are the IceCube Multi-Flavor Astrophysical Neutrino (ICEMAN) and Enhanced Starting Track Event Selection (ESTES) datasets. We employ a disk corona model and a power law flux assumption for our search. We present the status and preliminary outcome of our searches for neutrinos from these Seyfert galaxies.
