Constraints On the Size Evolution of Brightest Cluster Galaxies
Amy E. Nelson, Luc Simard, Dennis Zaritsky +2
We measure the luminosity profiles of 16 brightest cluster galaxies (BCGs) at using high resolution F160W NICMOS and F814W WFPC2 HST imaging. The heterogeneous samp…
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…
Are There Blue, Massive E/S0s at z < 1 ?: Kinematics of Blue Spheroidal Galaxy Candidates
Myungshin Im, S. M. Faber, Karl Gebhardt +5
Several recent studies find that 10 - 50% of morphologically selected field early-type galaxies at redshifts z <= 1 have blue colors indicative of recent star formation. Such ``blu…
