GEMS Survey Data and Catalog
J. A. R. Caldwell, D. H. McIntosh, H-W. Rix +14
We describe the data reduction and object cataloging for the GEMS survey, a large-area (800 arcmin^2) two-band (F606W and F850LP) imaging survey with the Advanced Camera for Survey…
Dry Mergers in GEMS: The Dynamical Evolution of Massive Early-Type Galaxies
Eric F. Bell, Thorsten Naab, Daniel H. McIntosh +16
We have used the 28'x 28' HST image mosaic from the GEMS (Galaxy Evolution from Morphology and SEDs) survey in conjunction with the COMBO-17 photometric redshift survey to constrai…
The Shear TEsting Programme 1: Weak lensing analysis of simulated ground-based observations
Catherine Heymans, Ludovic Van Waerbeke, David Bacon +22
The Shear TEsting Programme, STEP, is a collaborative project to improve the accuracy and reliability of all weak lensing measurements in preparation for the next generation of wid…
The Oxford-Dartmouth Thirty Degree Survey II: Clustering of Bright Lyman Break Galaxies - Strong Luminosity Dependent Bias at z=4
Paul D. Allen, Leonidas A. Moustakas, Gavin Dalton +5
We present measurements of the clustering properties of bright () z4 Lyman Break Galaxies (LBGs) selected from the Oxford-Dartmouth Thirty Degree Survey (ODT). We de…
GEMS: The Size Evolution of Disk Galaxies
Marco Barden, Hans-Walter Rix, Rachel S. Somerville +14
We combine HST imaging from the GEMS survey with photometric redshifts from COMBO-17 to explore the evolution of disk-dominated galaxies since z<1.1. The sample is comprised of all…
