Description of the talk:

Speaker: Professor Michael Shaevitz, Columbia University
Part of Nevis Labs' #ScienceOnHudson lecture series. Recorded Thu Nov 12, 2015

The IceCube project at the South Pole has melted eighty-six holes over 1.5 miles deep in the Antarctic icecap to be used as an astronomical observatory. Into each hole is lowered a string knotted with sixty basketball-sized light detectors that are sensitive to the shimmering blue light emitted in the surrounding clear ice when ghostly particles called neutrinos pass through the Earth.

We have recently discovered a flux of neutrinos reaching us from the cosmos with energies more than a million times those of the neutrinos produced at on earth with accelerators. They are astronomical messengers from the most violent processes in the universe; for example, giant black holes gobbling up stars in the heart of quasars and gamma-ray bursts, which are the biggest explosions since the Big Bang. The lecture will describe the telescope and work at the South Pole along with highlight the first scientific results.
