The first data from BOSS, the Baryon Oscillation Spectroscopic Survey led by Berkeley Lab scientists, is now available to the public. Spectroscopic data from over 500,000 galaxies up to 7 billion light years away, more than 100,000 quasars up to 11.5 billion light years away, and many thousands of other astronomical objects are included in the Sloan Digital Sky Survey’s Data Release 9. BOSS is the largest spectroscopic survey ever for measuring evolution of large-scale galactic structure. BOSS principal investigator David Schlegel, instrument scientist Natalie Roe, and data pipeline wrangler Stephen Bailey discuss the results here.
