Evolution of the Color-Magnitude Relation in Galaxy Clusters at z ~1 from the ACS Intermediate Redshift Cluster Survey (2008)

Mei, Simona, Holden, Brad P., Blakeslee, John P., Ford, Holland C., Franx, Marijn, Homeier, Nicole L., ...

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 defined and elliptical...

Spitzer/MIPS 24um Observations of Galaxy Clusters: An Increasing Fraction of Obscured Star-forming Members from z=0.02 to z=0.83 (2008)

Saintonge, Amélie, Tran, Kim-Vy H., Holden, Brad P.

We study the mid-infrared properties of 1315 spectroscopically confirmed members in eight massive (M>5x10^14 Msun) galaxy clusters covering the redshift range from 0.02 to 0.83. The selected clusters...

Evolution of the Color-Magnitude relation in High-Redshift Clusters: Early-type Galaxies in the Lynx Supercluster at z~1.26 (2006)

Mei, Simona, Holden, Brad P., Blakeslee, John P., Rosati, Piero, Postman, Marc, Jee, Myungkook J., ...

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 imaging in the WFC...
