First Light for BOSS – A New Kind of Search for Dark Energy :Berkeley Lab News Center
" 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."
