BOSS Quasars Unveil a New Era in the Expansion History of the Universe
Berkeley CA (SPX) Nov 16, 2012
BOSS, the Baryon Oscillation Spectroscopic Survey, is mapping a huge volume of space to measure the role of dark energy in the evolution of the universe. BOSS is the largest program of the third Sloan Digital Sky Survey (SDSS-III) and has just announced the first major result of a new mapping technique, based on the spectra of over 48,000 quasars with redshifts up to 3.5, meaning that light left these active galaxies up to 11.5 billion years in the past. "No technique for dark energy research has ... read more
