The Sloan Digital Sky Survey: Technical Summary
- D. York, J. Adelman, N. Yasuda
- Physics
- 27 June 2000
The Sloan Digital Sky Survey (SDSS) will provide the data to support detailed investigations of the distribution of luminous and nonluminous matter in the universe: a photometrically and…
THE SEVENTH DATA RELEASE OF THE SLOAN DIGITAL SKY SURVEY
- K. Abazajian, J. Adelman-McCarthy, D. Zucker
- Physics
- 3 December 2008
A series of improvements to the spectroscopic reductions are described, including better flat fielding and improved wavelength calibration at the blue end, better processing of objects with extremely strong narrow emission lines, and an improved determination of stellar metallicities.
Detection of the Baryon Acoustic Peak in the Large-Scale Correlation Function of SDSS Luminous Red Galaxies
- D. Eisenstein, I. Zehavi, D. York
- Physics
- 10 January 2005
We present the large-scale correlation function measured from a spectroscopic sample of 46,748 luminous red galaxies from the Sloan Digital Sky Survey. The survey region covers 0.72 h-3 Gpc3 over…
Sloan Digital Sky Survey: Early Data Release
- C. Stoughton, R. Lupton, Wei Zheng
- Physics
- 2002
The Sloan Digital Sky Survey (SDSS) is an imaging and spectroscopic survey that will eventually cover approximately one-quarter of the celestial sphere and collect spectra of ≈106 galaxies, 100,000…
The Sloan Digital Sky Survey Quasar Survey: Quasar Luminosity Function from Data Release 3
- G. Richards, M. Strauss, S. Snedden
- Physics
- 19 January 2006
We determine the number counts and z = 0-5 luminosity function for a well-defined, homogeneous sample of quasars from the Sloan Digital Sky Survey (SDSS). We conservatively define the most uniform…
The Sloan Digital Sky Survey View of the Palomar-Green Bright Quasar Survey
- S. Jester, D. Schneider, B. Yanny
- Physics
- 1 February 2005
We investigate the extent to which the Palomar-Green (PG) Bright Quasar Survey (BQS) is complete and representative of the general quasar population by comparing it with imaging and spectroscopy from…
Spectroscopic Target Selection in the Sloan Digital Sky Survey: The Quasar Sample
- G. Richards, X. Fan, D. York
- Physics
- 13 February 2002
We describe the algorithm for selecting quasar candidates for optical spectroscopy in the Sloan Digital Sky Survey. Quasar candidates are selected via their nonstellar colors in ugriz broadband…
Evidence for Reionization at z ∼ 6: Detection of a Gunn-Peterson Trough in a z = 6.28 Quasar
We present moderate-resolution Keck spectroscopy of quasars at z = 5.82, 5.99, and 6.28, discovered by the Sloan Digital Sky Survey (SDSS). We find that the Lyα absorption in the spectra of these…
Baryon Acoustic Oscillations in the Sloan Digital Sky Survey Data Release 7 Galaxy Sample
- W. Percival, B. Reid, I. Zehavi
- Physics
- 10 July 2009
The spectroscopic Sloan Digital Sky Survey (SDSS) Data Release 7 (DR7) galaxy sample represents the final set of galaxies observed using the original SDSS target selection criteria. We analyse the…
High-Redshift Quasars Found in Sloan Digital Sky Survey Commissioning Data
- X. Fan, M. Strauss, D. York
- Physics
- 16 March 1999
We present photometric and spectroscopic observations of 15 high-redshift quasars (z > 3.6) discovered from ∼140 deg2 of five-color (u′, g′, r′, i′, and z′) imaging data taken by the Sloan Digital…
