Average Properties of a Large Sample of z_abs ~ z_em associated Mg II Absorption Line Systems
D. Vanden Berk, P. Khare, D. G. York +16
We have studied a sample of 415 associated (z_ab z_em; relative velocity with respect to QSO <3000km/s) Mg II absorption systems with 1.0<=z_ab<=1.86, in the spectra of SDSS DR3 QS…
Combined analysis of the integrated Sachs-Wolfe effect and cosmological implications
Tommaso Giannantonio, Ryan Scranton, Robert G. Crittenden +4
We present a global measurement of the integrated Sachs-Wolfe (ISW) effect obtained by cross-correlating all relevant large scale galaxy data sets with the cosmic microwave backgro…
Biases in Virial Black Hole Masses: An SDSS Perspective
Yue Shen, Jenny E. Greene, Michael A. Strauss +2
We compile black hole (BH) masses for quasars in the redshift range included in the Fifth Data Release of the Sloan Digital Sky Survey (…
A Survey of z~6 Quasars in the SDSS Deep Stripe: I. a Flux-Limited Sample at z_{AB}<21
Linhua Jiang, Xiaohui Fan, James Annis +9
We present the discovery of five quasars at z~6 selected from 260 deg^2 of the Sloan Digital Sky Survey (SDSS) southern survey, a deep imaging survey obtained by repeatedly scannin…
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…
A New Quadruply Lensed Quasar: SDSSJ125107.57+293540.5
Issha Kayo, Naohisa Inada, Masamune Oguri +6
We report the discovery of a quadruply imaged quasar, SDSSJ125107.57+293540.5, selected from the Sloan Digital Sky Survey. Follow-up imaging reveals that the system consists of fou…
