Supporting Stations: South Pole Station
Research Locations: Dark Sector
The South Pole Telescope (SPT) project conducts cosmological research by measuring the intensity and polarization anisotropy of the Cosmic Microwave Background (CMB). By surveying 4,000 square degrees of the sky with high sensitivity in three wavelength bands, the telescope can detect galaxy clusters through the spectral distortion they impart on the CMB. Researchers will use the resulting catalog of galaxy clusters to set constraints on the mysterious dark energy that dominates the mass-energy density of the universe and is causing the expansion of the universe to accelerate.
Field Season Overview:
This year contract staff and project team members will complete installation of the shields, specifically the "wings" extending from the guard ring along the sides of the steel structure that supports the receiver cabin and secondary support. Unfinished tasking from last austral summer will be completed, calibrations and routine maintenance tasks will be performed. The SPT conducts observations all winter.
