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.
