UNIONS-3500 Weak Lensing: III. 2D Cosmological Constraints in Configuration Space
The episode discusses a paper titled "UNIONS-3500 Weak Lensing: III. 2D Cosmological Constraints in Configuration Space." Hosts discuss how researchers used cosmic shear analysis from the UNIONS-3500 catalogue to set cosmological constraints on S8, showing results consistent with Planck measurements. The discussion emphasizes the importance of rigorous systematic error mitigation and pipeline development for reliable results.
