Abstract: 

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 ?0.1?1 PeV neutrinos at IceCube. I discuss the detectability of these objects at the new High Altitude Water Cherenkov (HAWC) gamma ray detector. HAWC will view the North Bubble for ?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. I will discuss how the combination of results at HAWC and IceCube will substantiate the hadronic model, or constrain its spectral parameters.
