This will provide the definitive measurement of the low-redshift baryon acoustic oscillation (BAO) scale, and it will pioneer a powerful new method of measuring BAO at high redshift.
BigBOSS is a proposed international France-China-U.S.
Stage IV ground-based dark energy experiment. The project will use a new optical-NIR spectrograph (R=2300-6100) on the 4-m telescopes at Kitt Peak and Cerro Tololo, covering a 3-degree diameter field with 5000 individually-actuated fibers. 50 million targets over 24,000 deg^2 will measure BAO and redshift-space distortions with unprecedented accuracy.
