BOSS Quasars Unveil a New Era in the Expansion History of the Universe
November 12, 2012
Using the "Lyman-alpha forests" of tens of thousands of quasar spectra, the third Sloan Digital Sky Survey's Baryon Oscillation Spectroscopic Survey (BOSS), led by Lawrence Berkeley National Laboratory, has measured the large-scale structure of the early universe for the first time. No other technique can reach back over 10 billion years to probe baryon oscillations at a time when the expansion of the universe was still decelerating and dark energy had yet to turn on.
