Project description
High precision gravitational lensing maps to better probe the Universe
Maps of the gravitational lensing of the cosmic microwave background (CMB) allow astronomers to directly trace mass distribution across the Universe. Although recent measurements have established that CMB lensing signal is a powerful probe for cosmology, the potential of this method is not yet fully developed. The EU-funded CMBLENS project will analyse gravitational lensing CMB data derived from powerful ground-based experiments such as the Advanced ACTPol and the Simons Observatory. Using new analysis methods, scientists will reconstruct large-sky CMB lensing maps that are by an order of magnitude more precise than state-of-the-art measurements. Using the new high-fidelity lensing maps, CMBLENS will address key questions about the origin of the Universe, neutrino properties, nature of dark energy, and cosmic structure formation.
