Multi-Messenger Astronomy and The South Pole IceCube Neutrino Detector


Abstract

The IceCube Neutrino Observatory revealed the first evidence for high-energy neutrinos of astrophysical origin in 2013. That discovery represented the "first light” in a decades-old vision to observe the high-energy universe with neutrinos. I will review the motivation for using neutrinos as astronomical messenger particles and the evidence of astrophysical neutrinos from the IceCube detector. I will also present some recent developments that hold the promise of heralding in a new era in multi-messenger astronomy. I discuss how this new astronomy may help solve the century old mystery on the origin of the high energy cosmic rays and the extreme astrophysical processes that produce them.
