Dark Energy by ProQuest


A team led by researchers from Fermi National Accelerator Laboratory in Batavia, IL, is trying to probe the mysterious energy that makes up three quarters of the universe. The Dark Energy Survey is an optical imaging survey slated to begin in the fall of 2010 and continue for five years, said Josh Frieman, member, Fermilab's Theoretical Astrophysics Group. Fermilab researchers are now at work on the camera that will be used to collect optical images for study, Frieman said. The camera will be coupled with a telescope to allow for a survey of 15% of the sky to light levels that are faint enough to measure the colors of galaxies at so-called redshift one.
