Quasar Optical Variability in the Palomar-QUEST Survey
Anne Bauer, Charles Baltay, Paolo Coppi +4
The ensemble variability properties of nearly 23,000 quasars are studied using the Palomar-QUEST Survey. The survey has covered 15,000 square degrees multiple times over 3.5 years…
Blazar Optical Variability in the Palomar-QUEST Survey
Anne Bauer, Charles Baltay, Paolo Coppi +4
We study the ensemble optical variability of 276 FSRQs and 86 BL Lacs in the Palomar-QUEST Survey with the goal of searching for common fluctuation properties, examining the range…
Palomar-QUEST: A case study in designing sky surveys in the VO era
Matthew J. Graham, Roy Williams, S. G. Djorgovski +10
The advent of wide-area multicolour synoptic sky surveys is leading to data sets unprecedented in size, complexity and data throughput. VO technology offers a way to exploit these…
Golden gravitational lensing systems from the Sloan Lens ACS Survey. II. SDSS J1430+4105: A precise inner total mass profile from lensing alone
Thomas Eichner, Stella Seitz, Anne Bauer
We study the SLACS strong lensing system SDSSJ1430+4105 at z=0.285. The lensed source (z=0.575) of this system has a complex morphology with several subcomponents. Its subcomponent…
The QUEST Data Processing Software Pipeline
Peter Andrews, Charles Baltay, Anne Bauer +5
A program that we call the QUEST Data Processing Software Pipeline has been written to process the large volumes of data produced by the QUEST camera on the Samuel Oschin Schmidt T…
The QUEST Large Area CCD Camera
Charlie Baltay, David Rabinowitz, Peter Andrews +17
We have designed, constructed and put into operation a very large area CCD camera that covers the field of view of the 1.2 m Samuel Oschin Schmidt Telescope at the Palomar Observat…
Highly Variable Objects in the Palomar-QUEST Survey: A Blazar Search using Optical Variability
Anne Bauer, Charles Baltay, Paolo Coppi +11
We identify 3,113 highly variable objects in 7,200 square degrees of the Palomar-QUEST Survey, which each varied by more than 0.4 magnitudes simultaneously in two broadband optical…
Photo-z Quality Cuts and their Effect on the Measured Galaxy Clustering
Pol MartÃ, Ramon Miquel, Anne Bauer +1
Photometric galaxy surveys are an essential tool to further our understanding of the large-scale structure of the universe, its matter and energy content and its evolution. These s…
