The Ohio State University and their colleagues from the Dark Energy Survey (DES) collaboration have reached a new milestone mapping the growth of the universe from its infancy to present day.
The new results released last Thursday confirm the surprisingly simple but puzzling theory that the present universe is comprised of only 4% ordinary matter, 26% mysterious dark matter, and the remaining 70% in the form of mysterious dark energy, which causes the accelerating expansion of the universe.
The findings are based on data collected during the DES first year, which covers over 1300 square degrees of the sky or about the area of 6,000 full moons. DES uses the Dark Energy Camera mounted on the Blanco 4m telescope at the Cerro Tololo Inter-American Observatory high in the Chilean Andes.
The new results from the Dark Energy Survey will be presented by Kavli fellow Elisabeth Krause at the TeV Particle Astrophysics Conference in Columbus, Ohio, on Aug. 9, and by CCAPP’s Troxel at the International Symposium on Lepton Photon Interactions at High Energies in Guanzhou, China, on Aug. 10.
