Evolution of the Color-Magnitude Relation in Galaxy Clusters at z ~1 from the ACS Intermediate Redshift Cluster Survey

Simona Mei, Brad P. Holden, John P. Blakeslee +10

We apply detailed observations of the Color-Magnitude Relation (CMR) with the ACS/HST to study galaxy evolution in eight clusters at z~1. The early-type red sequence is well define…

Mass-Selection and the Evolution of the Morphology-Density Relation from z=0.8 to z=0

B. P. Holden, G. D. Illingworth, M. Franx +11

We examined the morphology-density relations for galaxy samples selected by luminosity and by mass in each of five massive X-ray clusters from z=0.023 to 0.83 for 674 spectroscopic…

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…

VLT and ACS observations of RDCS J1252.9-2927: dynamical structure and galaxy populations in a massive cluster at z=1.237

R. Demarco, P. Rosati, C. Lidman +26

We present results from an extensive spectroscopic survey, carried out with VLT FORS, and from an extensive multiwavelength imaging data set from the HST Advanced Camera for Survey…

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…

The Possible z=0.83 Precursors of z=0 M* Early-type Cluster Galaxies

B. P. Holden, M. Franx, G. D. Illingworth +8

We examine the distribution of stellar masses of galaxies in MS 1054-03 and RX J0152.7-1357, two X-ray selected clusters of galaxies at z=0.83. Our stellar mass estimates, from spe…
