주제 : Observing the neutrino sky with IceCube

발 표 요 약 :

  The recent discovery of high-energy astrophysical neutrinos through the IceCube Neutrino Telescope has opened up a new window to the Universe and allows us to observe the Cosmos in fundamentally new ways. This Summer we announced a compelling coincidence between a very energetic neutrino and gamma-ray emissions from a flaring blazar. This coincidence and a previous neutrino flare at the same position in the sky points to the first astrophysical source of high-energy neutrinos. IceCube is the worlds largest neutrino detector that utilizes a cubic kilometer of ultra-pure Antarctic ice at the geographic South Pole as detector medium. Latest results including the discovery of high-energy astrophysical neutrinos, multi-messenger searches, searches for neutrino point sources and transient sources as well as the search for dark matter will be reviewed. The mystery of the origin of the most energetic neutrinos ever observed will be discussed and the prospects for identifying cosmic accelerators with IceCube and potential upgrades will be reviewed.
