Title: Unveiling the Origin of High-Energy Neutrinos Observed by IceCube
Abstract:
" In 2012, the IceCube collaboration reported two PeV neutrino events.
Then, 26 more events were found in a follow-up analysis. Although
more statistics are needed to have conclusive evidence, they are
likely to include extraterrestrial signals. In this talk, I will try
to demystify the origin of this "IceCube excess". The current data
suggest that high-energy neutrinos are produced inside astrophysical
sources, while it is difficult to explain it with cosmogenic
neutrinos. I will also demonstrate the power of the multi-messenger
approach. It will be shown that present gamma-ray limits support
extragalactic scenarios and further observations can test Galactic
neutrino sources. Any viable astrophysical scenario relies on pp or
pgamma interaction as a neutrino production mechanism, and
discriminating them is also relevant to reveal the sources. In
particular, pp scenarios can be tested with multi-messenger data in
the next several years. I will discuss future prospects including
implications of some specific pgamma scenarios."
