Cosmological parameters from CMB temperature and E-mode polarization anisotropies with 2019 and 2020 data from the South Pole Telescope
ORAL
Abstract
SPT-3G, the third-generation camera on the South Pole Telescope, is being used to observe the cosmic microwave background (CMB) anisotropies to unprecedented depth at arcminute resolution. The temperature and E-mode polarization anisotropies of the CMB provide a wealth of information on the composition and evolution of the universe. Upcoming constraints on cosmological parameters from power spectrum analyses based on data collected in 2019/2020 will be comparable to Planck’s, while remaining mostly independent from the satellite experiment, thus allowing to test the consistency of the two data sets and potentially discover evidence of new physics. In this talk, I will describe the analysis pipeline, showcase our measurement and outline the steps towards cosmological parameters.<!-- notionvc: bcef5ff6-7dff-4a22-bd4f-9c7a6892bdc1 -->
