Cosmic Neutrinos in the IceCube Detector

Explore the groundbreaking discovery of astrophysical neutrinos in this 35-minute APS April Meeting 2014 plenary session talk by Naoko Kurahashi Neilson from the University of Wisconsin, Madison. Delve into the world of high-energy neutrinos and their potential astronomical sources, including active galactic nuclei, gamma-ray bursts, and supernova remnants. Learn about the IceCube Neutrino Observatory's innovative techniques for detecting neutrinos above 100 GeV in a cubic kilometer of ice at the South Pole. Discover how a new veto technique led to the first observation of astrophysical neutrinos, distinguishing them from atmospheric backgrounds. Examine the search for clustering events that could indicate individual sources, marking the birth of neutrino astronomy. Gain insights into cosmic neutrino astrophysics, diffuse flux, and the future of neutrino astronomy in relation to gamma-ray and X-ray astronomy.
