Dark Energy Survey (DES)

Cosmologists Josh Frieman and Risa Wechsler look back on the Dark Energy Survey, sharing how it’s paving the way for Rubin Observatory to dig deeper into some of the universe’s darkest mysteries.

The latest results combined weak lensing and galaxy clustering and incorporated four dark energy probes from a single experiment for the first time.

Wechsler is one of seven Stanford researchers to join the scholarly society, which works to promote science for public good.

The long and continuing quest to understand dark energy has entered exciting new territory.

Presented by Justin Myles. As the universe expanded from the Big Bang, regions where the density of matter was higher than average grew into galaxies and clusters of galaxies.

From the invisible world of elementary particles to the mysteries of the cosmos, recipients of this prestigious award for early career scientists explore nature at every level.

An analysis of the first three years of Dark Energy Survey data is consistent with predictions from the current best model of the universe. Nevertheless, hints remain from DES and other experiments that matter in the current universe is a...

For the first time, DES scientists can combine measurements of the distribution of matter, galaxies, and galaxy clusters to advance our understanding of dark energy.

Observations of dwarf galaxies around the Milky Way have yielded simultaneous constraints on three popular theories of dark matter.

Just like we orbit the sun and the moon orbits us, the Milky Way has satellite galaxies with their own satellites. Drawing from data on those galactic neighbors, a new model suggests the Milky Way should have an additional 100...

Matching up maps of matter and light from the Dark Energy Survey and Fermi Gamma-ray Space Telescope may help astrophysicists understand what causes a faint cosmic gamma-ray glow.
