Baryon Oscillation Spectroscopic Survey

(BOSS)
(survey of spatial distribution of luminous red galaxies and quasars)

The Baryon Oscillation Spectroscopic Survey (BOSS) is a part of Sloan Digital Sky Survey (SDSS)-III. It maps the distance and direction of luminous red galaxies (LRG) and Quasars (QSO) using normal Redshift (z)-based calculations. The data is then used to determine the location of acoustic waves which are thought to form the density variations that result in galaxies, i.e., Baryon Acoustic Oscillations (BAO). Areas dense in galaxies reveal a pattern of acoustic waves.
