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…
Evidence for reionization at z ∼ 6: Detection of a gunn-peterson trough in a z = 6.28 quasar
- R. Becker, Xiaohui Fan, D. York
- Physics
- 6 August 2001
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 Ly? absorption in the spectra of these…
The Broadband Optical Properties of Galaxies with Redshifts 0.02 < z < 0.22
- M. Blanton, D. Hogg, D. Weinberg
- Physics
- 23 September 2002
Using photometry and spectroscopy of 183,487 galaxies from the Sloan Digital Sky Survey, we present bivariate distributions of pairs of seven galaxy properties: four optical colors, surface…
A Wavelet-Based Algorithm for the Spatial Analysis of Poisson Data
- P. Freeman, V. Kashyap, R. Rosner, D. Lamb
- Physics
- 27 August 2001
Wavelets are scalable, oscillatory functions that deviate from zero only within a limited spatial regime and have average value zero, and thus may be used to simultaneously characterize the shape,…
THE THREE-DIMENSIONAL POWER SPECTRUM OF GALAXIES FROM THE SLOAN DIGITAL SKY SURVEY
- M. Tegmark, M. Blanton, D. York
- Physics
- 10 May 2004
We measure the large-scale real-space power spectrum P(k) by using a sample of 205,443 galaxies from the Sloan Digital Sky Survey, covering 2417 effective square degrees with mean redshift z ≈ 0.1.…
The Ensemble Photometric Variability of ~25,000 Quasars in the Sloan Digital Sky Survey
- D. Berk, B. Wilhite, D. Schlegel
- Physics
- 13 October 2003
Using a sample of over 25,000 spectroscopically confirmed quasars from the Sloan Digital Sky Survey, we show how quasar variability in the rest-frame optical/UV regime depends on rest-frame time lag,…
Early-Type Galaxies in the Sloan Digital Sky Survey. I. The Sample
- M. Bernardi, R. Sheth, D. York
- Physics
- 1 April 2003
A sample of nearly 9000 early-type galaxies, in the redshift range 0.01 ≤ z ≤ 0.3, was selected from the Sloan Digital Sky Survey (SDSS) using morphological and spectral criteria. This paper…
The fourth data release of the Sloan Digital Sky Survey
- J. Adelman-McCarthy, M. Agüeros, D. Zucker
- Physics
- 29 July 2005
This paper describes the Fourth Data Release of the Sloan Digital Sky Survey (SDSS), including all survey-quality data taken through 2004 June. The data release includes five-band photometric data…
