Analysis of CMB Temperature and E-mode Polarization Anisotropies with 2019 and 2020 Data from the South Pole Telescope

Autocorrelation and cross-correlation spectra of the temperature and E-mode polarization anisotropies (EE/TE/TT) of the CMB provide a wealth of information on the composition and evolution of the universe. While the Planck satellite experiment has already constrained parameters of the ΛCDM cosmological model to sub-percent precision using the anisotropies at relatively large angular scales, better measurements at small angular scales by a ground-based telescope such as the South Pole Telescope (SPT) can serve as a powerful consistency check and potentially discover evidence of new physics. The SPT-3G camera was installed in 2016/17 austral summer and was a significant upgrade from its predecessor, the SPTpol camera, with ten times more detectors. The instrument has been taking data stably at full capacity since 2019. Several analysis projects using the 2019 and 2020 dataset are underway, including substantially improving existing measurements of the EE/TE spectra and constraints on cosmological models from the SPT. In this talk, I will describe the status of the 2019 and 2020 EE/TE/TT analysis, show preliminary measurements of the spectra, and outline our next steps.
