Dark Energy Survey (DES)
PAC on Social Media
The Dark Energy Survey (DES) is a new survey of distant galaxies that aims to unravel the mystery of cosmic acceleration.
The DES uses multiple techniques to measure and study dark energy, the putative driving force of cosmic acceleration. Specifically, the DES studies dark energy through its impact on the abundance of galaxy clusters, weak gravitational lensing signals, type Ia supernovae and detections of large-scale correlations between galaxies. The combination of these various approaches will allow DES scientists to gain a more robust understanding of the current cosmological paradigm.
SLAC is directly involved in calibrating the DES imaging data, in running massive computer simulations of the Universe and DES data, and in several aspects of the analysis and processing of the DES data. The scientific focus at KIPAC includes weak gravitational lensing, clusters of galaxies, and galaxy evolution.
SLAC's DES participation is part of the research program of the SLAC–Stanford Kavli Institute for Particle Astrophysics and Cosmology.
