Physics Colloquium

Cosmology from Observations of the Cosmic Microwave Background

The cosmic microwave background (CMB) encodes information about both the early and late universe: it originates in the early universe and then traverses the entire observable cosmos before reaching us today. The South Pole Telescope (SPT) and the BICEP/Keck Array are millimeter-wave observatories at the South Pole used to measure the CMB. In this talk, I will present recent cosmological results from the SPT-3G survey, discuss our progress in testing inflationary models with BICEP/Keck and SPT-3G data, and introduce new field-level inference and machine learning techniques developed for next-generation CMB analyses.
