Explore precision measurements of the kinematic Sunyaev-Zel'dovich effect across different halo masses and redshifts using data from the Dark Energy Spectroscopic Instrument (DESI) and the Atacama Cosmology Telescope (ACT) in this 16-minute conference talk. Learn about cutting-edge observational techniques that combine multiple cosmological probes to advance our understanding of large-scale structure and cosmic microwave background physics. Discover how cross-correlation studies between galaxy surveys and CMB observations provide new insights into the motion of galaxy clusters and the underlying dark matter halos that host them. Examine the methodology for extracting kinematic signatures from the thermal Sunyaev-Zel'dovich effect, which occurs when cosmic microwave background photons are scattered by moving electrons in galaxy clusters. Understand how these measurements contribute to precision cosmology by providing independent constraints on cosmological parameters and testing our understanding of structure formation across cosmic time. Gain insights into the synergies between optical galaxy surveys and microwave observations, and how these multi-wavelength approaches are revolutionizing our ability to study the universe's large-scale structure and evolution.
