The Sloan Digital Sky Survey (SDSS) will provide the data to support detailed investigations of the distribution of luminous and non-luminous matter in the Universe: a photometrically and astrometrically calibrated digital imaging survey of π steradians above about Galactic latitude 30◦ in five broad optical bands to a depth of g′ ∼ 23, and a spectroscopic(More)
We discuss measurements of the properties of ∼10,000 asteroids detected in 500 deg of sky in the Sloan Digital Sky Survey (SDSS) commissioning data. The moving objects are detected in the magnitude range 14 < r< 21.5, with a baseline of ∼5 minutes, resulting in typical velocity errors of ∼3%. Extensive tests show that the sample is at least 98% complete,(More)
This paper describes the Fifth Data Release (DR5) of the Sloan Digital Sky Survey (SDSS). DR5 includes all survey quality data taken through June 2005 and represents the completion of the SDSS-I project (whose successor, SDSSII will continue through mid-2008). It includes five-band photometric data for 217 million objects selected over 8000 deg, and(More)
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 Gpc over 3816 deg and 0:16 < z < 0:47, making it the best sample yet for the study of large-scale structure. We find a well-detected peak in the correlation function at 100(More)
This paper describes the fourth data release of the Sloan Digital Sky Survey (SDSS), including all survey-quality data taken through June 2004. The data release includes five-band photometric data for 180 million objects selected over 6670 deg, and 673,280 spectra of galaxies, quasars, and stars selected from 4783 deg of that imaging data using the standard(More)
Despite the unique X-ray behavior of the compact bursting X-ray source MXB1730-335, the “Rapid Burster” (RB) in the highly reddened globular cluster Liller 1, to date there has been no known optical/IR counterpart for the object, no precise astrometric solution that correlates X-ray, radio, and optical positions and thus restricts the number of possible(More)
This is the second paper in a series aimed at finding high-redshift quasars from five-color (ugriz) imaging data taken along the Celestial Equator by the Sloan Digital Sky Survey (SDSS) during its commissioning phase. In this paper, we present 22 high-redshift quasars (z > 3.6) discovered from ∼ 250 deg of data in the spring Equatorial Stripe, plus(More)
Evidence is emerging that the luminous X-ray sources in the cores of globular clusters may often consist of, or perhaps even as a class be dominated by, ultracompact (P ∼ 1 hr) binary stars. To the two such systems already known, in NGC 6624 and NGC 6712, we now add evidence for two more. We detect large amplitude variability in the candidate optical(More)
1 2 SDSS QUASARS ABSTRACT We present photometric and spectroscopic observations of 15 high-redshift quasars (z > 3:6) discovered from 140 deg 2 of ve-color (u 0 g 0 r 0 i 0 z 0) imaging data taken by the Sloan Digital Sky Survey (SDSS) during its commissioning phase. The quasars are selected by their distinctive colors in SDSS multicolor space. Four of the(More)
We present photometric and spectroscopic observations of 15 high-redshift quasars (z > 3.6) discovered from ∼ 140 deg of five-color (ugriz) imaging data taken by the Sloan Digital Sky Survey (SDSS) during its commissioning phase. The quasars are selected by their distinctive colors in SDSS multicolor space. Four of the quasars have redshifts higher than 4.6(More)
