The SDSS-III's Baryon Oscillation Spectroscopic Survey (BOSS) will map the spatial distribution of luminous red galaxies (LRGs) and quasars to detect the characteristic scale imprinted by baryon acoustic oscillations in the early universe.
The SDSS-III's Baryon Oscillation Spectroscopic Survey (BOSS) was designed to measure the expansion rate of the Universe. It will map the spatial distribution of luminous red galaxies (LRGs) and quasars to map the spatial distribution and detect the characteristic scale imprinted by baryon acoustic oscillations in the early universe.
