Descripción
The IceCube Neutrino Observatory has detected high-energy astrophysical
neutrinos in the TeV-PeV range. These neutrinos have an isotropic
distribution on the sky, and therefore likely originate from extragalactic
sources. 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 1016 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 present an update on the
IceCube stacking analysis searching for high-energy neutrinos from hard
X-ray sources sampled from the Swift-BAT AGN Spectroscopic Survey (BASS).
