Description
The IceCube Neutrino Observatory has detected a diffuse flux of high-energy astrophysical neutrinos in the TeV-PeV range. These neutrinos likely originate from extragalactic sources given their apparent isotropic distribution. Active Galactic Nuclei (AGN) form a class of astronomical objects which are promising neutrino source candidates given their high electromagnetic luminosity and potential ability to accelerate cosmic rays up to energies larger than 10$^{16}$ eV. Interactions of these cosmic rays within the AGN environment are expected to produce both neutrinos and pionic gamma rays. Some hadronic models of AGN emission suggest that such gamma rays can in turn interact with the dense photon fields of AGN and cascade down to hard X-rays and MeV gamma rays. We will present our plan to perform a stacking analysis and a catalog search for point sources with IceCube data to find possible signatures of high-energy neutrinos from hard X-ray sources sampled from the $\textit{Swift}$-BAT AGN Spectroscopic Survey (BASS).
