Multi-messenger study of the Fermi BubblesLili Yang
, predavanje na tuji univerzi
Opis: 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). 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 and how sensitive Cherenkov Telescope Array(CTA) is to the bubbles.
