Discovery of Two Gravitationally Lensed Quasars with Image Separations of 3 Arcseconds from the Sloan Digital Sky Survey
Masamune Oguri, Naohisa Inada, Joseph F. Hennawi +15
We report the discovery of two doubly-imaged quasars, SDSS J100128.61+502756.9 and SDSS J120629.65+433217.6, at redshifts of 1.838 and 1.789 and with image separations of 2.86'' an…
Large Scale Clustering of Sloan Digital Sky Survey Quasars: Impact of the Baryon Density and the Cosmological Constant
Kazuhiro Yahata, Yasushi Suto, Issha Kayo +13
We report the first result of the clustering analysis of Sloan Digital Sky Survey (SDSS) quasars. We compute the two-point correlation function (2PCF) of SDSS quasars in redshift s…
The Small-scale Clustering of Luminous Red Galaxies via Cross-Correlation Techniques
Daniel J. Eisenstein, Michael Blanton, Idit Zehavi +5
We present the small-scale (0.2h^{-1} to 7h^{-1} Mpc) cross-correlations between 32,000 luminous early-type galaxies and a reference sample of 16 million normal galaxies from the S…
Cosmic homogeneity demonstrated with luminous red galaxies
David W. Hogg, Daniel J. Eisenstein, Michael R. Blanton +4
We test the homogeneity of the Universe at with the Luminous Red Galaxy (LRG) spectroscopic sample of the Sloan Digital Sky Survey. First, the mean number of LRG…
Rotation Velocities of Two Low Luminosity Field Galaxies
James Pizagno, Michael R. Blanton, David H. Weinberg +2
We present H-alpha rotation curves of two low luminosity field galaxies with r-band absolute magnitudes M_r=-13.9^{+0.8}_{-0.5} and M_r=-14.7^{+0.3}_{-0.2} (for h=0.7; the large er…
The Third Data Release of the Sloan Digital Sky Survey
K. Abazajian et al.
This paper describes the Third Data Release of the Sloan Digital Sky Survey (SDSS). This release, containing data taken up through June 2003, includes imaging data in five bands ov…
