A Survey of z>5.7 Quasars in the Sloan Digital Sky Survey IV: Discovery of Seven Additional Quasars
Xiaohui Fan, Michael A. Strauss, Gordon T. Richards +27
We present the discovery of seven quasars at z>5.7, selected from ~2000 deg^2 of multicolor imaging data of the Sloan Digital Sky Survey (SDSS). The new quasars have redshifts z fr…
SDSSJ103913.70+533029.7: A Super Star Cluster in the Outskirts of a Galaxy Merger
G. R. Knapp, C. A. Tremonti, C. M. Rockosi
We describe the serendipitous discovery in the spectroscopic data of the Sloan Digital Sky Survey of a star-like object, SDSSJ103913.70+533029.7, at a heliocentric radial velocity…
The White Dwarf Luminosity Function from SDSS Imaging Data
Hugh C. Harris, Jeffrey A. Munn, Mukremin Kilic +16
A sample of white dwarfs is selected from SDSS DR3 imaging data using their reduced proper motions, based on improved proper motions from SDSS plus USNO-B combined data. Numerous S…
The Milky Way Tomography with SDSS: I. Stellar Number Density Distribution
Mario Juric, Zeljko Ivezic, Alyson Brooks +23
Abridged: We estimate the distances to ~48 million stars detected by the Sloan Digital Sky Survey and map their 3D number density distribution in 100 < D < 20 kpc range over 6,500…
Photometric Covariance in Multi-Band Surveys: Understanding the Photometric Error in the SDSS
Ryan Scranton, Andrew J. Connolly, Alexander S. Szalay +5
In this paper we describe a detailed analysis of the photometric uncertainties present within the Sloan Digital Sky Survey (SDSS) imaging survey based on repeat observations of app…
The Fourth Data Release of the Sloan Digital Sky Survey
J. K. Adelman-McCarthy et al.
This paper describes the fourth data release of the Sloan Digital Sky Survey (SDSS), including all survey-quality data taken through June 2004. The data release includes five-band…
