Efficient Photometric Selection of Quasars from the Sloan Digital Sky Survey: II. ~1,000,000 Quasars from Data Release Six
Gordon T. Richards, Adam D. Myers, Alexander G. Gray +6
We present a catalog of 1,172,157 quasar candidates selected from the photometric imaging data of the Sloan Digital Sky Survey (SDSS). The objects are all point sources to a limiti…
Efficient Photometric Selection of Quasars from the Sloan Digital Sky Survey: 100,000 z<3 Quasars from Data Release One
Gordon T. Richards, Robert C. Nichol, Alexander G. Gray +15
We present a catalog of 100,563 unresolved, UV-excess (UVX) quasar candidates to g=21 from 2099 deg^2 of the Sloan Digital Sky Survey (SDSS) Data Release One (DR1) imaging data. Ex…
An Empirical Algorithm for Broad-band Photometric Redshifts of Quasars from the Sloan Digital Sky Survey
Michael A. Weinstein, Gordon T. Richards, Donald P. Schneider +7
We present an empirical algorithm for obtaining photometric redshifts of quasars using 5-band Sloan Digital Sky Survey (SDSS) photometry. Our algorithm generates an empirical model…
Red and Reddened Quasars in the Sloan Digital Sky Survey
Gordon T. Richards, Patrick B. Hall, Daniel E. Vanden Berk +12
We investigate the continuum and emission line properties of 4576 SDSS quasars as a function of their optical/UV SEDs. The optical/UV color distribution of our sample is roughly Ga…
Optical and Radio Properties of Extragalactic Sources Observed by the FIRST and SDSS Surveys
Z. Ivezic, K. Menou, M. Strauss +6
We discuss the optical and radio properties of 30,000 FIRST sources positionally associated with an SDSS source in 1230 deg of sky. The majority (83%) of the FIRST sources iden…
Photometric Redshifts of Quasars
Gordon T. Richards, Michael A. Weinstein, Donald P. Schneider +3
We demonstrate that the design of the Sloan Digital Sky Survey (SDSS) filter system and the quality of the SDSS imaging data are sufficient for determining accurate and precise pho…
