Observations and Theoretical Implications of the Large Separation Lensed Quasar SDSS J1004+4112
M. Oguri, N. Inada, C. R. Keeton +25
We study the recently discovered gravitational lens SDSS J1004+4112, the first quasar lensed by a cluster of galaxies. It consists of four images with a maximum separation of 14.62…
Sloan Digital Sky Survey Spectroscopic Lens Search. I. Discovery of Intermediate-Redshift Star-Forming Galaxies Behind Foreground Luminous Red Galaxies
Adam S. Bolton, Scott Burles, David J. Schlegel +2
We present a catalog of 49 spectroscopic strong gravitational lens candidates selected from a Sloan Digital Sky Survey sample of 50996 luminous red galaxies. Potentially lensed sta…
A Snapshot Survey for Gravitational Lenses Among z>=4.0 Quasars: I. The z>5.7 Sample
Gordon T. Richards, Michael A. Strauss, Bartosz Pindor +7
Over the last few years, the Sloan Digital Sky Survey (SDSS) has discovered several hundred quasars with redshift between 4.0 and 6.4. Including the effects of magnification bias,…
Continuum and Emission-Line Properties of Broad Absorption Line Quasars
Timothy A. Reichard, Gordon T. Richards, Patrick B. Hall +6
We investigate the continuum and emission-line properties of 224 broad absorption line quasars (BALQSOs) with 0.9<z<4.4 drawn from the Sloan Digital Sky Survey (SDSS) Early Data Re…
Physical Evidence for Dark Energy
R. Scranton, A. J. Connolly, R. C. Nichol +17
We present measurements of the angular cross-correlation between luminous red galaxies from the Sloan Digital Sky Survey and the cosmic microwave background temperature maps from t…
Stellar and Dynamical Masses of Ellipticals in the Sloan Digital Sky Survey
N. Padmanabhan, U. Seljak, M. A. Strauss +9
We study the variation of the dark matter mass fraction of elliptical galaxies as a function of their luminosity, stellar mass, and size using a sample of 29,469 elliptical galaxie…
