Description
The IceCube Neutrino Observatory is a cubic kilometer neutrino detector located 2 km under the South Pole. Since it became operational in the early 2010s, IceCube has detected the most energetic neutrinos ever seen (from TeV to PeV -- solar neutrinos are ~ MeV for scale). It is clear that these high energy neutrinos are astrophysical in origin, but how are they being produced? It is thought that these neutrinos are emitted by the most explosive astrophysical phenomena in the Universe such as accreting super massive black holes and colliding neutron stars to name some examples. This talk will focus on how IceCube came to discover the diffuse flux of high energy astrophysical neutrinos and its continuing search for their sources, as well as discussing the role of neutrinos in multi-messenger astronomy.
