From Nature, Sept. 5, 2017: Maps of the cosmic microwave background have become iconic representations of the early universe. But when the Dark Energy Survey collaboration unveiled the analysis of their first year of data last month, many felt that a new era had started.

At the 2017 APS Division of Particles and Fields meeting at Fermilab, Stanford scientist Daniel Gruen reported the year-one results from the Dark Energy Survey, including the most accurate measurement ever made of the present large-scale structure of the universe. You can view a video of Gruen’s talk, which is now available online.

From the DOE Office of Science, June 21, 2017: Dark Energy Survey Director Josh Frieman appears in this Office of Science article, which surveys research projects that will help us better understand the phenomenon that is accelerating the universe’s expansion.

Scientists furthered studies of the Higgs boson, neutrinos, dark matter, dark energy and cosmic inflation and continued the search for undiscovered particles, forces and principles.
