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…

Lyman break galaxies, Lya emitters and a radio galaxy in a protocluster at z=4.1
Roderik A. Overzier, R. J. Bouwens, N. J. G. Cross +17
We present deep HST/ACS observations in g,r,i,z towards the z=4.1 radio galaxy TN J1338-1942 and its overdensity of >30 spectroscopically confirmed Lya emitters (LAEs). We select 6…
