The South Pole Telescope (SPT) is a 10 m telescope located ~1 km from the geographic South Pole. The telescope and its 3 generations of receivers have been used to make high resolution observations of the cosmic microwave background (CMB).  Argonne has played a key role in both the construction of the SPT camera (having fabricated the 90 GHz detectors for the 2nd receiver, SPTpol, as well as the entire ~16k bolometer SPT-3G focal plane) and in the data analysis. CPAC members are particularly interested in utilizing SPT observations to constrain cosmological models via measurements of the primary and secondary anisotropies of the CMB, the thermal and kinematic Sunyaev–Zel’dovich effect signals from galaxy clusters, weak gravitational lensing of the CMB, and via quantifying correlations of many of these observables with large scale structure tracers from other surveys such as DES and, in the near future, LSST.
