Weak Lensing Mass Calibration with DECam: The Most Precise Mass—Scaling Relation Measurement To Date [3.64 MB PDF]

Thomas McClintock

Galaxy clusters are a powerful probe of cosmology. Observations of galaxy clusters using DECam made by the Dark Energy Survey (DES) have taken significant steps in order to allow galaxy clusters to become a powerful probe of the large scale structure of the Universe. Using gravitational weak lensing, DES has precisely measured the mean cluster mass -- optical richness scaling relation to 5% accuracy. This is the most stringent scaling relation of galaxy clusters performed to date, and has allowed for competitive constraints on the matter density and clustering amplitude of the Universe.
