Probing the Late-Time Universe with the South Pole Telescope - Secondary Anisotropies and Lensing Cross-Correlations

Explore advanced cosmological research through this 37-minute conference talk examining how the South Pole Telescope investigates secondary anisotropies and lensing cross-correlations to probe the late-time universe. Learn about cutting-edge observational techniques and analysis methods used to study cosmic microwave background secondary effects and their correlations with large-scale structure. Discover how multi-probe approaches combining CMB observations with other cosmological tracers advance our understanding of astrophysics and cosmology. Gain insights into the Sunyaev-Zel'dovich effect, gravitational lensing measurements, and cross-correlation studies that reveal properties of the universe's evolution. Understand the role of the South Pole Telescope in modern cosmological surveys and how its unique capabilities contribute to precision measurements of cosmic structure formation. Examine the statistical methods and theoretical frameworks used to extract cosmological parameters from these complex observational datasets. This presentation was delivered as part of the New Synergies in Multi-Probe Cosmology conference at the Kavli Institute for Theoretical Physics, focusing on innovative methods to combine multiple observational probes across the electromagnetic spectrum from radio to X-ray wavelengths.
