A Search for Extended Ultraviolet Disk (XUV-disk) Galaxies in the Local Universe
David A. Thilker, Luciana Bianchi, Gerhardt Meurer +26
We have initiated a search for extended ultraviolet disk (XUV-disk) galaxies in the local universe. Herein, we compare GALEX UV and visible--NIR images of 189 nearby (D40 Mpc) S…
Photometric Redshift Estimation on SDSS Data Using Random Forests
Samuel Carliles, Tamás Budavári, Sebastien Heinis +2
Given multiband photometric data from the SDSS DR6, we estimate galaxy redshifts. We employ a Random Forest trained on color features and spectroscopic redshifts from 80,000 random…
Measuring the Baryon Acoustic Oscillation scale using the SDSS and 2dFGRS
Will J. Percival, Shaun Cole, Daniel J. Eisenstein +4
We introduce a method to constrain general cosmological models using Baryon Acoustic Oscillation (BAO) distance measurements from galaxy samples covering different redshift ranges,…
The Sloan Digital Sky Survey Quasar Catalog IV. Fifth Data Release
Donald P. Schneider, Patrick B. Hall, Gordon T. Richards +41
We present the fourth edition of the Sloan Digital Sky Survey (SDSS) Quasar Catalog. The catalog contains 77,429 objects; this is an increase of over 30,000 entries since the previ…
Clustering of High Redshift () Quasars from the Sloan Digital Sky Survey
Yue Shen, Michael A. Strauss, Masamune Oguri +13
(Abridged) We study the two-point correlation function of a uniformly selected sample of 4,426 luminous optical quasars with redshift selected over 4041 deg…
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…
