October 30, 2017: Summer team begins arriving at the South Pole

 

 

July 22, 2013: B-mode polarization detected with SPTpol. The B-mode polarization induced by gravitational lensing is detected in SPTpol data by first creating a template of lensing B modes then cross-correlating this template with the SPTpol B-mode data. The template is created using the measured SPTpol E-mode polarization and an estimate of the lensing potential from Herschel-SPIRE maps of the cosmic infrared background. The plots shows the result of this cross-correlation in black bars (with results from consistency tests as green and orange bars), along with the prediction for this signal using our current best-fit cosmological model as the dashed line. The grey bars are the result of a null test.

November, 2017: SPT-3G camera upgrade begins.

Scientists working on the South Pole Telescope (SPT) project have made the long-journey to Antarctica to begin work on the SPT-3G camera. The goal for this summer season is to bring the SPT-3G camera up to full sensitivity following its initial installation in Jan 2017. The upgraded camera will have more than 10x more detectors than its predecessor, SPTpol, and will be used to make an ultra-sensitive map of CMB polarization across 2500 sq. degrees.
