Abstract / Description: 

The IceCube Neutrino Observatory at the US South Pole Station is a cubic-kilometer scale neutrino detector, using a billion tons of ultra-pure Antarctic ice as a Cherenkov radiator. IceCube detects over 100,000 neutrinos per year, at energies ranging from a few GeV to several PeV. Most of these are produced in the Earth's atmosphere, but at the highest energies we have discovered a neutrino flux of cosmic origin. Although their exact sources remain unclear, the level of this flux suggests that hadron accelerators produce a considerable fraction of the energy in the non-thermal universe. We will discuss the IceCube Observatory, the observations of high energy neutrinos, and their significance.


 

Held Tuesdays at 4:30 pm in the William R. Hewlett Teaching Center, room 201.
