SDSS Data Management and Photometric Quality Assessment
Z. Ivezic, R. H. Lupton, D. Schlegel +24
We summarize the Sloan Digital Sky Survey data acquisition and processing steps, and describe runQA, a pipeline designed for automated data quality assessment. In particular, we sh…
Cosmological parameter analysis including SDSS Ly-alpha forest and galaxy bias: constraints on the primordial spectrum of fluctuations, neutrino mass, and dark energy
U. Seljak, A. Makarov, P. McDonald +18
We combine the constraints from the recent Ly-alpha forest and bias analysis of the SDSS with previous constraints from SDSS galaxy clustering, the latest supernovae, and WMAP . Co…
The Lyman-alpha Forest Power Spectrum from the Sloan Digital Sky Survey
Patrick McDonald, Uros Seljak, Scott Burles +8
We measure the power spectrum, P_F(k,z), of the transmitted flux in the Ly-alpha forest using 3035 high redshift quasar spectra from the Sloan Digital Sky Survey. This sample is al…
Near-Infrared Photometry and Spectroscopy of L and T Dwarfs: the Effects of Temperature, Clouds, and Gravity
G. R. Knapp, S. K. Leggett, X. Fan +3
We present JHK photometry and spectroscopy for a sample of newly identified L and T dwarfs from the Sloan Digital Sky Survey (SDSS) and known dwarfs from the SDSS and the Two Micro…
The Second Data Release of the Sloan Digital Sky Survey
K. Abazajian et al.
The Sloan Digital Sky Survey has validated and made publicly available its Second Data Release. This data release consists of 3324 square degrees of five-band (u g r i z) imaging d…
The Distribution of Quasars and Galaxies in Radio Color-Color and Morphology Diagrams
Z. Ivezic, R. J. Siverd, W. Steinhardt +12
We positionally match the 6 cm GB6, 20 cm FIRST and NVSS, and 92 cm WENSS radio catalogs and find 16,500 matches in ~3,000 deg2 of sky. Using this unified radio database, we constr…
