Surface Brightness Evolution of Cluster Galaxies
David Schade
Surface brightness evolution has been detected in elliptical galaxies (consistent with passive evolution models of old stellar populations) and in disk galaxies (presumably due to…
CFRS XIV: Spectral Properties Of Field Galaxies Up To z = 1
F. Hammer, H. Flores, S. J. Lilly +6
The spectral properties of more than 400 CFRS galaxies and their changes over the redshift interval 0 - 1.3 are investigated. Emission line intensities and equivalent widths for ac…
Dynamical Perturbation Theory and the Auxiliary Field Method
B. Holdom, Qing Wang
By introducing auxiliary fields, which by their quantum numbers vanish in perturbation theory, we relate the dynamical perturbation theory of Pagels and Stokar and a successful gau…
Evolution of Cluster Ellipticals at 0.2 < z < 1.2 from Hubble Space Telescope Imaging
David Schade, L. Felipe Barrientos, Omar Lopez-Cruz
Two-dimensional surface photometry derived from Hubble Space Telescope imaging is presented for a sample of 225 early-type galaxies (assumed to be cluster members) in the fields of…
The Las Campanas Redshift Survey Galaxy-Galaxy Autocorrelation Function
D. L. Tucker, A. Oemler, R. P. Kirshner +7
Presented are measurements of the observed redshift-space galaxy-galaxy autocorrelation function, xi(s), for the Las Campanas Redshift Survey (LCRS). For separations 2.0/h Mpc < s…
The Dynamical Equilibrium of Galaxy Clusters
Carlberg, Yee, Ellingson +9
If a galaxy cluster is effectively in dynamical equilibrium then all galaxy populations within the cluster must have distributions in velocity and position that individually reflec…
