April Flowers for redOrbit.com - Your Universe Online The largest-ever 3-D map of massive galaxies and distant black holes was released this week in the hopes that it will help explain the mysteries of "dark matter" and "dark energy." This new sky map is the work of the Sloan Digital Sky Survey III (SDSS-111) collaboration. SDSS-III is mission is to map the Milky Way, search for extrasolar planets, and solve the mystery of dark matter. The research team began to gather data in 2008 for...

Led by Berkeley Lab scientists, the Sloan Digital Sky Survey´s BOSS is bigger than all other spectroscopic surveys combined for measuring the universe's large-scale structure The Third Sloan Digital Sky Survey (SDSS-III) has issued Data Release 9 (DR9), the first public release of data from the Baryon Oscillation Spectroscopic Survey (BOSS). In this release BOSS, the largest of SDSS-III's four surveys, provides spectra for 535,995 newly observed galaxies, 102,100 quasars, and 116,474...

BOSS, the Baryon Oscillation Spectroscopic Survey, is the most ambitious attempt yet to map the expansion history of the Universe using the technique known as baryon acoustic oscillation (BAO). A part of the Sloan Digital Sky Survey III (SDSS-III), BOSS achieved "first light" on the night of September 14-15, when it acquired data with an upgraded spectrographic system across the entire focal plane of the Sloan Foundation 2.5-meter telescope at Apache Point Observatory in New Mexico. BOSS is...

Using a map of more than 4,000 luminous quasars in the distant universe, scientists from the Sloan Digital Sky Survey (SDSS-II) have shown that these brilliant beacons are strongly clumped, with huge quasar superclusters separated by vast stretches of empty space. The strong clustering shows that the quasars lie within massive concentrations of dark matter. "Previous maps showed that more nearby quasars cluster like 'normal' galaxies," explained Princeton University graduate student Yue...
