Mapping the History of Cosmic Structure Growth with CMB Lensing Cross-Correlations

Explore the history of cosmic structure growth through CMB lensing cross-correlations in this 39-minute conference talk by Alex Krolewski from UC Berkeley. Learn how cosmic microwave background lensing can be combined with other observational probes to map the evolution of large-scale structure throughout cosmic history. Discover innovative methods for cross-correlating CMB lensing signals with galaxy surveys and other tracers to constrain cosmological parameters and understand the growth of cosmic structure over time. Examine the latest observational techniques and analysis methods used to extract cosmological information from these multi-probe approaches. Understand how CMB lensing serves as a powerful tool for studying dark matter distribution and the expansion history of the universe. Gain insights into the theoretical framework underlying these measurements and their implications for our understanding of dark energy, modified gravity, and the standard cosmological model. Recorded as part of the New Synergies in Multi-Probe Cosmology conference at the Kavli Institute for Theoretical Physics, this presentation showcases cutting-edge research in observational cosmology and the synergistic potential of combining different astronomical observations.
