Query: A multi-messenger study of the Fermi Bubbles: very high energy gamma
  rays and neutrinos   The Fermi Bubbles have been imaged in sub-TeV gamma rays at Fermi-LAT, and,
if their origin is hadronic, they might have been seen with low statistics in
$\sim 0.1- 1$ PeV neutrinos at IceCube. We discuss the detectability of these
objects at the new High Altitude Water Cherenkov (HAWC) gamma ray detector.
HAWC will view the North Bubble for $\sim 2-3$ hours a day, and will map its
spectrum at 0.1-100 TeV. For the hard primary proton spectrum required to
explain five events at IceCube, a high significance detection at HAWC will be
achieved in less than 30 days. The combination of results at HAWC and IceCube
will substantiate the hadronic model, or constrain its spectral parameters.
