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…
Evolution of the Color-Magnitude relation in High-Redshift Clusters: Early-type Galaxies in the Lynx Supercluster at z~1.26
Simona Mei, Brad P. Holden, John P. Blakeslee +10
Color-magnitude relations have been derived in the clusters RX J0849+4452 and RX J0848+4453 at z~1.26. The color-magnitude relation was determined from Advanced Camera for Surveys…
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…
HST/ACS Multiband Coronagraphic Imaging of the Debris Disk around Beta Pictoris
D. A. Golimowski, D. R. Ardila, J. E. Krist +40
(Abridged.) We present F435W (B), F606W (Broad V), and F814W (Broad I) coronagraphic images of the debris disk around Beta Pictoris obtained with HST's Advanced Camera for Surveys.…
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…
