SPT-3G: Measurements of CMB Lensed TT/TE/EE Power Spectra with 2019 and 2020 Temperature and Polarization Data

Temperature and E-mode polarization anisotropies of the cosmic microwave background (CMB) that we observe today are results of various physical phenomena such as the acoustic oscillations of the photon-baryon fluid in early universe and gravitational lensing of the photons during their travels to us. And the autocorrelation and cross-correlation spectra of these anisotropies (the TT/TE/EE spectra) provide a wealth of information on cosmology. While the Planck satellite experiment has already constrained parameters of the standard cosmological model, ΛCDM, to sub-percent precision using the TT/TE spectra at large angular scales, better measurements of the TE/EE spectra at small angular scales by ground-based telescopes such as the South Pole Telescope (SPT) can serve as a powerful consistency check and can test extension models of ΛCDM. SPT-3G is the third-generation imaging instrument on the telescope and was installed in 2017. We have been analyzing the data taken in 2019 and 2020 austral winter seasons to significantly improve our previous measurements of the TE/EE spectra at small angular scales. In this talk, we report the status of the analysis and discuss results that we have obtained so far. These results will be combined with 2019-2020 SPT-3G CMB lensing reconstruction results to produce some of the tightest constraints on cosmological parameters to date.
