October 1, 2018: Successful 2018 season nearly finished with SPT-3G camera, 1-month until first austral flights arrive.



December 23, 2011: The two-dimensional marginalized constraints on the sum of the neutrino masses versus the number of relativistic species. Contours show the 68% and 95% confidence regions for the WMAP7+H0+BAO (gray, dashed) dataset, then including the SPT power spectrum measurements from Keisler et al. (2011) (blue, dashed), and next including the SPT cluster abundance measurements from Benson et al. (2011) (orange, solid). The dashed vertical line shows the expected value for three neutrino species.

New: Jobs!



October, 2018: The SPT-3G camera has nearly completed it's 2018 observing season! Winter-overs Joshua Montgomery and Adam Jones have nearly finished a successful 2018 austral-winter observing season at the South Pole! They will continue using SPT-3G to observe the 1500 sq. deg. survey patch for another month, before being relieved by a small austral-summer crew who will perform maintenance and improvements on the telescope and camera.

  The South Pole Telescope is funded through the National Science Foundation and the Department of Energy Office of Science. NSF DOE
