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…
Counts of Low-redshift SDSS Quasar Candidates
Z. Ivezic, R. H. Lupton, D. E. Johnston +10
We analyze the counts of low-redshift quasar candidates selected using nine-epoch SDSS imaging data. The co-added catalogs are more than 1 mag deeper than single-epoch SDSS data, a…
Halo Structure Traced by SDSS RR Lyrae
Z. Ivezic, R. H. Lupton, D. Schlegel +6
We discuss the density and radial velocity distributions of over 3000 candidate RR Lyrae stars selected by various methods using Sloan Digital Sky Survey data for about 1000 deg^2…
Weak Lensing Mass of Nearby Clusters of Galaxies
M. Joffre, P. Fischer, J. Frieman +9
We describe first results of a project to create weak lensing mass maps for a complete, X-ray luminosity-limited sample of 19 nearby (z < 0.1) southern galaxy clusters scheduled fo…
