Discovery of a Ringlike Dark Matter Structure in the Core of the Galaxy Cluster Cl 0024+17
M. J. Jee, H. C. Ford, G. D. Illingworth +13
We present a comprehensive mass reconstruction of the rich galaxy cluster Cl 0024+17 at z~0.4 from ACS data, unifying both strong- and weak-lensing constraints. The weak-lensing si…
The Formation Epoch of Early-Type Galaxies in the z ~ 0.9 CL1604 Supercluster
N. L. Homeier, S. Mei, J. P. Blakeslee +12
We analyse the cluster color-magnitude relation (CMR) for early-type galaxies in two of the richer clusters in the z ~ 0.9 supercluster system to derive average ages and formation…
Clusters at Half Hubble Time: Galaxy Structure and Colors in RXJ0152.7-1357 and MS1054-03
J. P. Blakeslee, B. P. Holden, M. Franx +12
We study the photometric and structural properties of spectroscopically confirmed members in the two massive X-ray--selected z=0.83 galaxy clusters MS1054-03 and RXJ0152-1357 using…
Weak-Lensing Detection at z~1.3: Measurement of the Two Lynx Clusters with Advanced Camera for Surveys
M. J. Jee, R. L. White, H. C. Ford +4
(Abridged) We present a HST/ACS weak-lensing study of RX J0849+4452 and RX J0848+4453, the two most distant (at z=1.26 and z=1.27, respectively) clusters yet measured with weak-len…
Evolution of the Color-Magnitude Relation in High-Redshift Clusters: Blue Early-Type Galaxies and Red Pairs in RDCS J0910+5422
S. Mei, J. P. Blakeslee, S. A. Stanford +17
The color-magnitude relation has been determined for the RDCS J0910+5422 cluster of galaxies at redshift z = 1.106. Cluster members were selected from HST ACS images, combined with…
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,…
