On the high-energy IceCube neutrinos
Sergio Palomares Ruiz (Instituto de Física Corpuscular, University of Valencia)

The observation of the first high-energy neutrinos in the IceCube detector at the South Pole has signaled the beginning of neutrino astronomy. After four years of data taking, 53 neutrino events with energies between 20 TeV and 2 PeV have provided the first evidence for the existence of an extraterrestrial neutrino flux at more than 6 sigma. The discovery of this flux has motivated a large number of studies in the literature to unravel their origin, from different scenarios within standard cosmic-ray sources to more exotic possibilities. In this talk, I will describe the evolution of these data and their main features and I will present the results of statistical analyses of different scenarios.
