Explore how cosmic microwave background radiation can be used as a backlight to study large-scale structure in this 53-minute conference talk by Emmanuel Schaan from the Galileo Galilei Institute. Learn about innovative techniques for mitigating baryonic effects that complicate cosmological observations and measurements. Discover how CMB lensing and other observational methods can provide cleaner insights into the distribution of matter in the universe by effectively "backlighting" large-scale structures. Gain understanding of the challenges posed by baryonic physics in cosmological surveys and how novel approaches using the CMB can help overcome these observational obstacles to better constrain cosmological parameters and dark matter properties.
