Abstract

Neutrinos offer a unique view of the high-energy Universe. Unlike photons or charged particles, neutrinos can travel across the Universe without interference as they are not absorbed by matter, nor are their trajectories bent by magnetic fields. IceCube is the world's largest neutrino detector, instrumenting a cubic kilometre of ice below the South Pole. With IceCube, we use neutrino observations to study the high-energy universe and, in particular, to investigate the origins of the most energetic cosmic rays. The relativistic jets which are produced from the accretion of matter by a supermassive black hole are thought to harbour some of the highest-energy processes in the Universe today. In September last year IceCube issued an alert after the detection of a neutrino which traced back to the location of the blazar TXS 0506+056. This alert was followed up the gamma-ray detectors Fermi and Magic who observed that TXS 0506+056 was undergoing a period of particularly energetic activity providing evidence that TXS 0506+056 was the first known source of high-energy neutrinos and cosmic rays. In this seminar I will report on this exciting new result from IceCube.
