Austin Schneider, MIT, "IceCube and the high-energy neutrino landscape"
The IceCube Neutrino Observatory is the world's largest neutrino detector, instrumenting a cubic kilometer of ice at the geographic South Pole. IceCube announced the detection of a diffuse flux of astrophysical neutrinos in 2013, including the highest energy neutrinos ever detected. Since then, the energy spectrum and composition of this flux have been the subject of intense study; however, its precise origin remains unknown. In September 2017, IceCube observed a neutrino in coincidence with a flaring blazar, signaling the era of neutrino astronomy and widening the field of multi-messenger astronomy. I will cover IceCube's most recent astrophysical flux measurements, related investigations of neutrino sources, and future plans.
