Photometric observations in the VRcIc bands spanning the time interval between 2004 September 22 and 2010 November 23 were performed with six instruments on...
QSO 2237+0305 VR Light Curves from Gravitational LensES International Time Project Optical Monitoring
We present VR observations of QSO 2237+0305 conducted by the Gravitational Lensing International Time Project collaboration from 1999 October 1 to 2000 February...
Quantifying high z galaxy selection and visibility with the COSMOPACK tool
We have developed COSMOPACK, a set of tools that transform images of real galaxies to depict their appearance at a given redshift as observed with a given...
Quantitative Morphological Analysis of Galaxies at Intermediate Red Shift: Clues to Galaxy Evolution
We have developed morphological analysis software for studying galaxies from low to high redshifts. This code is designed to extract quantitative information...
Quantitative morphological analysis of the Hubble Deep Field North and Hubble Deep Field South - I. Early- and late-type luminosity-size relations of galaxies out to z~ 1
Based on drizzled F606W and F814W images, we present quantitative structural parameters in the V-band rest-frame for all galaxies with z 1 and I814(AB) 24.5...
Quantitative Morphology of Galaxies in the Core of the Coma Cluster
We present a quantitative morphological analysis of 187 galaxies in a region covering the central 0.28 deg2 of the Coma Cluster. Structural parameters from the...
Quantitative Morphology of the Intermediate-Redshift Galaxy Cluster Abell 2443 from Ground-based Imaging: Evidence for a Galaxy Concentration Index Correlation with Cluster Density
We present broadband photometry and provide a quantitative analysis of the structure of galaxies in the inner region of the Abell Cluster 2443 (z~0.1). The...
Between 1999 February and 2000 April, the QUEST1 variability survey collected 69 drift scans of the same region of high Galactic latitude sky. The scans cover a...
QUEST1 variability survey (QVS). III. (Rengstorf+, 2009)
QUEST1 constructed a 16-chip CCD camera to be used on the 1m Schmidt telescope at the Llano del Hato National Astronomical Observatory in Venezuela. Normally...
