Query: Investigation of Ultra-Luminous Infrared Galaxies as Obscured
  High-Energy Neutrino Source Candidates   Ultra-Luminous Infrared Galaxies (ULIRGs) are the most luminous objects in
the infrared sky. With infrared luminosities exceeding $10^{12}$ solar
luminosities, ULIRGs contain strong star formation regions which could power
hadronic acceleration. Moreover, a significant fraction of ULIRGs have been
found to host Active Galactic Nuclei, which could also be a source of hadronic
acceleration. Furthermore, such high infrared luminosities indicate that large
amounts of dust are present in these objects. In the presence of hadronic
acceleration, this dust not only represents an excellent target for high-energy
neutrino production through the pp-channel, but it could also attenuate a
significant fraction of the gamma rays that are produced in this process. This
could relieve the apparent tension between the diffuse IceCube neutrino flux
and the diffuse gamma-ray flux measured by Fermi-LAT. We present our source
selection criteria and IceCube sensitivities in view of a search for
high-energy neutrinos from these so far unexplored objects.
