Chihway Chang, University of Chicago, "Mapping the Cosmos with the Dark Energy Survey - sneak peek of the first year weak lensing results"
KICP colloquium: May 31 @ 3:30 PM, ERC 161
Weak gravitational lensing, or weak lensing, is one of the most powerful tools in cosmology. The technique relies on measuring accurately the shape of a large number of galaxies, and statistically translating the shape measurements into (dark matter) mass distributions.
