The Evolution of Stellar Mass in the NICMOS UDF and the CFHTLS Deep Fields

Stephen Gwyn, F. D. A. Hartwick, Anudeep Kanwar +2

We measure the build-up of the stellar mass of galaxies from z=6 to z=1. Using 15 band multicolour imaging data in the NICMOS Ultra Deep Field we derive photometric redshifts and m…

Tracing Cosmic Evolution with the Las Campanas Distant Cluster Survey

Anthony H. Gonzalez, Julianne J. Dalcanton, Amy E. Nelson +3

The Las Campanas Distant Cluster Survey (LCDCS), which contains over 1000 cluster candidates at z>0.3, is a unique sample with which to probe the evolution of both cluster galaxies…

A Deep Keck Spectral Survey of Cl0024+1654 at z=0.4

Anne J. Metevier, David C. Koo, Luc Simard +1

We have undertaken a Keck spectral survey of galaxies to R~24 near the central region of Cl0024+1654 at z=0.4. The spectral resolution and slits have been selected to yield kinemat…

A Pilot Study of the Tully-Fisher Relation in Cl0024+1654 at z=0.4

Anne J. Metevier, David C. Koo, Luc Simard

We present the first determination of the Tully-Fisher relation (TFR) for a distant galaxy cluster. We have measured internal kinematics of seven members of Cl0024+1654 from spatia…

Brightest Cluster Galaxies and the Las Campanas Distant Cluster Survey

Dennis Zaritsky, Amy E. Nelson, Luc Simard +2

We present our study of the evolution of brightest cluster galaxies based on data from the Las Campanas Distant Cluster Survey (Gonzalez et al. 2001) and HST optical and IR imaging…

Breaking the Disk/Halo Degeneracy with Gravitational Lensing

Ariyeh H. Maller, Luc Simard, Puragra Guhathakurta +4

The degeneracy between the disk and the dark matter contribution to galaxy rotation curves remains an important uncertainty in our understanding of disk galaxies. Here we discuss a…
