Looking for the origin of astrophysical neutrinos
Time: 2:30 pm - 3:30 pm
Place: 5310 Chamberlin Hall
Speaker: Dmitri Semikoz, APC Paris
Abstract: IceCube neutrino telescope recently discovered astrophysical neutrinos in the energy range from 10 TeV to 3 PeV. This discovery challenged existed theoretical models due to unexpected observation of soft 1/E^{2.5} neutrino spectrum. Together with limits from diffuse gamma-ray flux measured with Fermi LAT this excluded most of existed theoretical predictions. In my talk I'll discuss significance of the galactic component observation in the 4 years IceCube data. Also I'll review theoretical models, which can explain observed data both with Galactic and extra-galactic sources of neutrinos. Finally, I'll present model, which at the same time explain Ultra-High Energy Cosmic Ray protons, astrophysical neutrinos and diffuse gamma-ray background.
