Cosmology from the Dark Energy Survey

ORAL  · Invited

Abstract

The Dark Energy Survey is testing our cosmological model with multiple probes on the optical imaging data it has recently finished collecting. It has simultaneously constrained the cosmic expansion history (using Type-Ia Supernovae and Baryonic Acoustic Oscillations) and the linear and non-linear growth of structure in the Universe. I will present our latest results from these largely independent experiments, with a focus on the accurate measurement and interpretation of higher-order structure from gravitational lensing. A joint view of these statistics and the rapidly increasing and improving data has allowed DES to begin to deliver on the promise of optical surveys as a leading probe of cosmology.
