Current and Future Massive Redshift Survey

Colloquium: Astronomy Colloquia | November 14 | 4:10 p.m. | 2 LeConte Hall


David Schlegel, LBNL

Department of Astronomy


The Baryon Acoustic Oscillation Survey (BOSS) on the Sloan Telescope is the world’s largest redshift survey. When it completes next year, it will have mapped 1.5 million galaxies and 160,000 quasars. I will describe the results from the key project, measuring the scale of the universe to percent-level precision at redshifts 0.3, 0.6 and 2.4.

Starting in 2014, the Extended BOSS survey on the Sloan Telescope will extend the redshift reach and cosmological results.

Starting in 2018, the DESI project will map 25 million galaxies and quasars over the northern sky. I will describe the DESI design and construction status.
