Title: IceCube: The First Decade of Neutrino Astronomy
Abstract: Below the geographic South Pole, the IceCube project has transformed one cubic kilometer of natural Antarctic ice into a neutrino detector. IceCube detects more than 100,000 neutrinos per year in the one to a million GeV energy range. Among those, we have isolated high-energy neutrinos originating beyond our Galaxy, with a flux that exceeds the extragalactic high-energy gamma-ray flux observed by astronomers in a similar energy range. With a decade of data, we have identified their first sources, which point to supermassive black holes at the centers of active galaxies powering the cosmic ray accelerators that produce high-energy neutrinos. Machine learning techniques eventually revealed that our own Milky Way emits neutrinos but, interestingly, it is not a prominent feature in the neutrino sky as it is in all wavelengths of light. We will also review the study of the neutrinos themselves, emphasizing oscillation measurements.
