Feedback and Brightest Cluster Galaxy Formation: ACS Observations of the Radio Galaxy TN J1338--1942 at z=4.1
Andrew W. Zirm, R. A. Overzier, G. K. Miley +12
We present deep optical imaging of the z=4.1 radio galaxy TN J1338--1942 obtained using the ACS on-board HST. The radio galaxy is known to reside within a large galaxy overdensity…

Evolution in the Cluster Early-type Galaxy Size-Surface Brightness Relation at z =~ 1
B. P. Holden, J. P. Blakeslee, M. Postman +7
We investigate the evolution in the distribution of surface brightness, as a function of size, for elliptical and S0 galaxies in the two clusters RDCS J1252.9-2927, z=1.237 and RX…

The Morphology - Density Relation in z ~ 1 Clusters
M. Postman, M. Franx, N. Cross +10
We measure the morphology--density relation (MDR) and morphology-radius relation (MRR) for galaxies in seven z ~ 1 clusters that have been observed with the Advanced Camera for Sur…
