The South Pole Telescope (SPT) is a 10-meter millimeter-wave telescope located at the South Pole in Antarctica. It is the largest telescope in Antarctica. The SPT is being used to make detailed maps of the cosmic microwave background - light from the early hot Universe three hundred thousand years after the Big Bang. Please contact Christian Reichardt for more information about the project.

The South Pole Telescope (SPT) is currently embarked on its second survey, using a polarization sensitive camera, SPTpol. A new camera, SPT-3G, with 10 times more detectors is expected to be installed in early 2016.

The SPT has three major science goals:  (1) to search for the inflationary gravitational waves that have been called the "smoking gun of Inflation", (2) to use gravitational lensing to make maps of all matter in the Universe and learn about the masses of the neutrinos from the properties of these mass map, and (3) to measure the abundance of galaxy clusters -- the largest collapsed objects in the Universe -- and use the measured abundances to study dark energy.
