Clustering of Star-forming Galaxies Near a Radio Galaxy at z=5.2
Roderik A. Overzier, G. K. Miley, R. J. Bouwens +13
We present HST/ACS observations of the most distant radio galaxy known, TN J0924-2201 at z=5.2. This radio galaxy has 6 spectroscopically confirmed Lya emitting companion galaxies,…
The Morphology - Density Relation in z ~ 1 Clusters
M. Postman, M. Franx, N. Cross +10
We measure the morphology--density relation (MDR) and morphology-radius relation (MRR) for galaxies in seven z ~ 1 clusters that have been observed with the Advanced Camera for Sur…
The Transformation of Cluster Galaxies at Intermeidate Redshift
N. L. Homeier, R. Demarco, P. Rosati +17
We combine imaging data from the Advanced Camera for Surveys (ACS) with VLT/FORS optical spectroscopy to study the properties of star-forming galaxies in the z=0.837 cluster CL0152…
Strong Lensing Analysis of A1689 from Deep Advanced Camera Images
Tom Broadhurst, Narciso Benitez, Dan Coe +6
We analyse deep multi-colour Advanced Camera images of the largest known gravitational lens, A1689. Radial and tangential arcs delineate the critical curves in unprecedented detail…
