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…
The Surprisingly Steep Mass Profile of Abell 1689, from a Lensing Analysis of Subaru Images
Tom Broadhurst, Masahiro Takada, Keiichi Umetsu +4
Subaru observations of A1689 (z=0.183) are used to derive an accurate, model-independent mass profile for the entire cluster, r<2 Mpc/h, by combining magnification bias and distort…
Probing Halos of Galaxies at Very Large Radii using Background QSOs
Stephanie Cote, Rosemary Wyse, Claude Carignan +2
(ABRIDGED) Gaseous halos of nine nearby galaxies (with redshifts cz < 6000 km/s) were probed at large galactocentric radii using background quasars observed with HST GHRS and STIS.…
Resolving the Stellar Populations in a z=4 Lensed Galaxy
Andrew J. Bunker, Leonidas A. Moustakas, Marc Davis
We present deep near-infrared Keck/NIRC imaging of a recently-discovered z=4.04 galaxy (Frye & Broadhurst 1998). This is lensed by the rich foreground cluster Abell~2390 (z~0.23) i…
Gravitational Lens Magnification and the Mass of Abell 1689
A. N. Taylor, S. Dye, T. J. Broadhurst +2
We present the first application of lens magnification to measure the absolute mass of a galaxy cluster; Abell 1689. The absolute mass of a galaxy cluster can be measured by the gr…
Mapping Cluster Mass Distributions via Gravitational Lensing of Background Galaxies
T. J. Broadhurst, A. N. Taylor, J. A. Peacock
We present a new method for measuring the projected mass distributions of galaxy clusters. The gravitational amplification is measured by comparing the joint distribution in redshi…
