The South Pole Telescope (SPT) is a new 10-meter telescope at the Amundsen-Scott South Pole research station. Taking advantage of the exceptionally clear, dry, and stable atmosphere at the South Pole, the SPT will map large areas of the sky with high sensitivity at millimeter and sub-millimeter wavelengths.

Goal of the CMB Polarization hubThe goal of the CMB Polarization Hub is to coordinate and synthesize results from a number of experiments searching for B-mode polarization in order to minimize systematic errors due to backgrounds and maximize signal. With these combined results in hand, the probability of detection is maximized or the very strongest possible limits on inflationary gravitational waves will be established.
