HTTP:: BOSS Begins Its Quest for Dark Energy
--------
During the night of September 14-15, the Baryon Oscillation Spectroscopic Survey (BOSS) experienced its first light, in an event that marked the beginning of a new type of quest for dark matter. The new method relies on the now-emerging technology known as baryon acoustic oscillation (BAO), which may have the ability to clear up questions related to the expansion history of our Universe. BOSS is a part of the Sloan Digital Sky Survey III (SDSS-III), ScienceDaily reports. “Baryon oscillation is a fast-maturing method for measuring dark energy in a way that's complementary to the proven techniques of supernova cosmology. The data from BOSS will be some of the best ever obtained on the large-scale structure of the Universe,†David Schlegel, who is the principal investigator for the BOSS project, explains. The expert, along with colleague Martin White, survey scientist, and Natalie Roe, instrument scientist, is based at the US Department of Energy's (DOE) Lawrence Berkele!
y National Laboratory (Berkeley Lab). University of Arizona Professor Daniel Eisenstein is the director of the SDSS-III. The first light for BOSS was achieved across the entire focal plane of the Sloan Foundation 2.5-meter telescope, at the Apache Point Observatory, in New Mexico. The resulting image featured more than 800 galaxies and ...
