The Sloan Digital Sky Survey Quasar Lens Search. II. Statistical Lens Sample from the Third Data Release
Naohisa Inada, Masamune Oguri, Robert H. Becker +31
We report the first results of our systematic search for strongly lensed quasars using the spectroscopically confirmed quasars in the Sloan Digital Sky Survey (SDSS). Among 46,420…
The Sloan Digital Sky Survey Quasar Lens Search. III. Constraints on Dark Energy from the Third Data Release Quasar Lens Catalog
Masamune Oguri, Naohisa Inada, Michael A. Strauss +31
We present cosmological results from the statistics of lensed quasars in the Sloan Digital Sky Survey (SDSS) Quasar Lens Search. By taking proper account of the selection function,…
The Sloan Digital Sky Survey Quasar Lens Search. I. Candidate Selection Algorithm
Masamune Oguri, Naohisa Inada, Bartosz Pindor +8
We present an algorithm for selecting an uniform sample of gravitationally lensed quasar candidates from low-redshift (0.6<z<2.2) quasars brighter than i=19.1 that have been spectr…
SDSSJ102111.02+491330.4: A Newly Discovered Gravitationally Lensed Quasar
Bart Pindor, Daniel J. Eisenstein, Michael D. Gregg +24
We report follow-up observations of two gravitational lens candidates identified in the Sloan Digital Sky Survey (SDSS) dataset. We have confirmed that SDSS J102111.02+491330.4 is…
A Snapshot Survey for Gravitational Lenses Among z>=4.0 Quasars: II. Constraints on the 4.0<z<4.5 Quasar Population
Gordon T. Richards, Zoltan Haiman, Bartosz Pindor +7
We report on i-band snapshot observations of 157 Sloan Digital Sky Survey (SDSS) quasars at 4<z<5.4 using the Advanced Camera for Surveys on the Hubble Space Telescope (HST) to sea…
SDSS J0246-0825: A New Gravitationally Lensed Quasar from the Sloan Digital Sky Survey
Naohisa Inada, Scott Burles, Michael D. Gregg +14
We report the discovery of a new two-image gravitationally lensed quasar, SDSS J024634.11-082536.2 (SDSS J0246-0825). This object was selected as a lensed quasar candidate from the…
