Description
CMB lensing robustly measures the growth of large-scale structure, providing a powerful test of our cosmological model and of new physics. I will preview the final release of Atacama Cosmology Telescope lensing measurements, which, through several innovations including daytime analysis, will reach state-of-the-art precision and significantly advance determinations of structure growth, neutrino mass, and key cosmological parameters. I will also briefly summarize recent progress in CMB lensing measurements with the new Simons Observatory, which will be central to future lensing science.
