Description
The South Pole Telescope (SPT) is a 10-meter millimeter-wavelength telescope located at the geographic South Pole, one of the world's premier sites for millimeter-wave observations. The SPT has been used to conduct several generations of wide-field high resolution cosmic microwave background (CMB) surveys including the 2500-square-degree SPT-SZ survey, the SPTpol 500d and ECS surveys, and now the 10,000 square-degree SPT-3G survey.
One of the primary objectives of these surveys has been the construction of mass-limited samples of galaxy clusters identified via the thermal Sunyaev- Zel'dovich (SZ) effect, through which massive clusters imprint subtle temperature distortions on the CMB. The abundance of such clusters is a powerful cosmological probe as it depends sensitively upon both the expansion history of the universe and the growth of density fluctuations. In this talk I will discuss these datasets, including progress on the SPT-3G cluster sample. I will also highlight areas of synergy with eROSITA.
