Mass Comparisons of the z ∼ 0 . 3 CNOC Cluster Sample
Results are presented from a detailed analysis of optical and X-ray observations of moderate-redshift galaxy clusters from the Canadian Network for Observational Cosmology (CNOC) subsample of the EMSS. The combination of extensive optical and deep X-ray observations of these clusters make them ideal candidates for multiwavelength mass comparison studies. X-ray surface brightness profiles of 14 ...
متن کاملX-ray Mass Estimates at z∼0.3 for the CNOC Cluster Sample
Results are presented from the analysis of ROSAT HRI and PSPC observations of the CNOC subsample of the EMSS high redshift galaxy clusters. X-ray surface brightness profiles of 14 clusters with 0.17 < z < 0.55 are constructed and fit to isothermal β models. Where possible, we use both the HRI and PSPC data to constrain the fit. Under the assumptions of isothermality, hydrostatic equilibrium, an...
متن کاملEVOLUTION OF CLUSTER AND FIELD ELLIPTICALS AT 0.2 < z < 0.6 IN THE CNOC CLUSTER SURVEY
Two-dimensional surface photometry has been done for 166 early-type galaxies (bulge/total luminosity B/T > 0.6) in 3 fields of the Canadian Network for Observational Cosmology (CNOC) cluster survey. These galaxies are either spectroscopically confirmed members of clusters at z = 0.23 (45 galaxies), 0.43 (22), and 0.55 (16) or field galaxies in the same redshift range. An additional 51 early-typ...
متن کاملVelocity Dispersions of Cnoc Clusters and the Evolution of the Cluster Abundance
We present the results of the analysis of the internal velocity dispersions, σv, for the sample of 16 distant galaxy clusters (0.17∼< z∼< 0.55) provided by the Canadian Network for Observational Cosmology (CNOC). Different σv estimates are provided, all based on an interlopers removal algorithm, which is different from that originally applied by Carlberg et al. (1996). We find that all such met...
متن کاملErratum to: Sample size calculations for cluster randomised controlled trials with a fixed number of clusters
BACKGROUND Cluster randomised controlled trials (CRCTs) are frequently used in health service evaluation. Assuming an average cluster size, required sample sizes are readily computed for both binary and continuous outcomes, by estimating a design effect or inflation factor. However, where the number of clusters are fixed in advance, but where it is possible to increase the number of individuals...
