The IceCube neutrino observatory, a cubic-kilometer particle detector at the
South Pole, first announced the discovery of an astrophysical flux of
high-energy neutrinos in the TeV-PeV range in 2013, followed in 2017 by the
detection of a high-energy neutrino event in temporal and directional
correlation with the flaring gamma-ray blazar TXS 0506+056. This observation,
combined with archival neutrino detections in 2014-2015, has provided
compelling evidence for the detection of the first high-energy astrophysical
neutrino source. A promising way of detecting additional sources is to
correlate neutrino detections with sources where a hadronic electromagnetic
signature is observed. If blazars are a significant source of neutrinos, the
high-energy gamma rays produced in pionic decays in coincidence with the
neutrinos may cascade in the strong photons fields present in blazar jets,
leading to strong emission in the hard X-ray to MeV gamma-ray energy range. We
here present plans for a search for neutrino emission from a large sample of
hard X-ray sources from the BAT AGN Spectroscopic Survey (BASS).
