Theory seminar: High-Energy Neutrinos
Michael Kachelriess, NTNU [slides]
The IceCube Collaboration announced 2012 evidence for the first detection of extraterrestrial neutrinos. Meanwhile, the discovery of a extraterrestrial neutrino flux (of surprisingly large magnitude) has been established. After a review of the basic ideas of high-energy neutrino astrophysics, I discuss possible sources for these neutrinos and their signatures. I discuss the neutrino yield from collisions of cosmic ray nuclei with gas and the possibility that Galactic sources can explain the IceCube excess. I review also the cascade bound on extragalactic neutrinos and its consequences.
