Chandra X-ray Observations of Newly Discovered, z ~ 1 Clusters from the Red-Sequence Cluster Survey
Amalia Hicks, Erica Ellingson, Mark Bautz +3
Observational studies of cluster evolution over moderate redshift ranges (to z ~ 1) are a powerful tool for constraining cosmological parameters, yet a comprehensive knowledge of t…
Population Gradients in Galaxy Clusters at 0.2 < Z < 0.6
E. Ellingson, H. Lin, H. K. C. Yee +1
We present a principal component analysis of galaxy spectra from the CNOC sample of rich X-ray luminous clusters at 0.18 < z < 0.55. Composite radial distributions of different ste…
The Omega_M-Omega_Lambda Constraint from CNOC Clusters
R. G. Carlberg, H. K. C. Yee, E. Ellingson +14
The CNOC redshift survey of galaxy clusters measures Omega_M from Omega_e(z)= M/L x j/ρ_c which can be applied on a cluster-by-cluster basis. The mass-to-light ratios, M/L, are est…
Star Formation in High Redshift Galaxies
Jill Bechtold, Richard Elston, Howard K. C. Yee +2
Observations of the high redshift Universe, interpreted in the context of a new generation of computer simulated model Universes, are providing new insights into the processes by w…
Results on Galaxy Evolution from the CNOC2 Field Galaxy Redshift Survey
H. Lin, H. K. C. Yee, R. G. Carlberg +9
The CNOC2 Field Galaxy Redshift Survey presently contains some 5000 galaxy redshifts, plus extensive UBgRI photometry, and is the largest galaxy sample at moderate redshifts 0.1 <…
Omega_M and the CNOC Surveys
R. G. Carlberg, H. K. C. Yee, H. Lin +15
The CNOC1 cluster survey measures Omega_M via Oort's method, Omega_M= M/L x j/rho_c, where M/L is the field mass-to-light ratio, j is the field luminosity density and rho_c is the…
