Katherine Rawlins: The IceCube Observatory: exploring the high-energy universe

The IceCube Neutrino Observatory is an array of 86 strings of photomultiplier tubes buried deep in the ice sheet of Antarctica, designed to pick up the Cherenkov light from the collisions of passing high-energy neutrinos.  Neutrinos, as well as cosmic rays and gamma rays, can bring information from extreme and explosive sites in the universe.  In this talk, we'll meet this extraordinary detector and its capabilities.
