Galaxy Clustering Evolution in the CNOC2 High-Luminosity Sample
R. G. Carlberg, H. K. C. Yee, S. L. Morris +5
The redshift evolution of the galaxy two-point correlation function is a fundamental cosmological statistic. To identify similar galaxy populations at different redshifts, we selec…
Velocity Dispersions of CNOC Clusters and the Evolution of the Cluster Abundance
S. Borgani, M. Girardi, R. G. Carlberg +2
We present the results of the analysis of the internal velocity dispersions, σ_v, for the CNOC sample of distant galaxy clusters, based on an interlopers removal algorithm, which i…
Differential Galaxy Evolution in Cluster and Field Galaxies at z=0.3
Michael L. Balogh, S. L. Morris, H. K. C. Yee +2
(abridged) We measure spectral indices for 1823 galaxies in the CNOC1 sample of fifteen X-ray luminous clusters at 0.18<z<0.55, to investigate the mechanisms responsible for differ…
A Quantitative Measure of the Richness of Galaxy Clusters
H. K. C. Yee, Omar Lopez-Cruz
Using photometric catalogs from wide-field CCD images, we derive the cluster-galaxy correlation amplitudes, Bgc, for 47 low-redshift Abell clusters. We apply a number of tests to e…
The CNOC2 Field Galaxy Luminosity Function I: A Description of Luminosity Function Evolution
H. Lin, H. K. C. Yee, R. G. Carlberg +5
We examine the evolution of the galaxy luminosity function (LF) using a sample of over 2000 galaxies, with 0.12 < z < 0.55 and 17.0 < Rc < 21.5, drawn from the Canadian Network for…
