Testing the Standard Cosmological Model with HSC-Y3 Cosmic Shear Data and CMB Data

Watch this 13-minute conference talk examining the Standard Cosmological Model through analysis of HSC-Y3 cosmic shear data combined with cosmic microwave background (CMB) data. Learn how Ryo Terasawa from Kavli IPMU at the University of Tokyo presents cutting-edge research testing fundamental cosmological theories using observational data from the Hyper Suprime-Cam survey's third-year dataset. Discover the methodologies for combining cosmic shear measurements with CMB observations to probe the structure and evolution of the universe. Explore how multi-probe cosmological analysis techniques advance our understanding of dark matter, dark energy, and the overall cosmological framework. Gain insights into the latest developments in large-scale structure surveys and their applications in validating or challenging current cosmological models. 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 approaches to combining multiple astronomical observations for enhanced cosmological understanding.
