Understand
We discuss the possibility that the IceCube neutrino telescope might be observing the Fermi Bubbles.
- If the bubbles discovered in gamma rays originate from accelerated protons, they should be strong emitters of high energy (> GeV) neutrinos.
- These neutrinos are detectable as shower- or track-like events at a Km^3 neutrino observatory.
- For a primary cosmic ray cutoff energy at or above 10 PeV, the Fermi Bubble flux substantially exceeds the atmospheric background, and could account for up to ~ 4-5 of the 28 events detected above ~ 30 TeV at IceCube.
