SUMMARY:First Evidence of High-Energy Extraterrestrial Neutrinos at Ic
eCube\, NPAC (Nuclear/Particle/Astro/Cosmo) Forum\, Claudio Kooper\, U
W - Madison
DESCRIPTION:The spectrum of cosmic rays includes the most energetic pa
rticles ever observed. The mechanism of their acceleration and their s
ources are\, however\, still mostly unknown. Observing astrophysical n
eutrinos can help solve this problem. Because neutrinos are produced i
n hadronic interactions and are neither absorbed nor deflected\, they
will point directly back to their source. This talk will cover searche
s for high-energy neutrinos (> 100 TeV) at the IceCube neutrino observ
atory\, which have recently produced the first evidence for a flux bey
ond standard expectations from neutrinos generated in the Earth's atmo
sphere. This includes the detection of two events with energies above
1 PeV -- the highest energy neutrinos ever observed. The current statu
s of these astrophysical neutrino searches and prospects for the futur
e will be discussed.
