The velocity and mass distribution of clusters of galaxies from the CNOC1 cluster redshift survey
In the context of the CNOC1 cluster survey, redshifts were obtained for galaxies in 16 clusters. The resulting sample is ideally suited for an analysis of the internal velocity and mass distribution of clusters. Previous analyses of this dataset used the Jeans equation to model the projected velocity dispersion profile. However, the results of such an analysis always yield a strong degeneracy b...
متن کاملStarburst Galaxies in Clusters
The nature of the starburst phenomenon in galaxies is investigated using a narrow band color system designed to study color evolution in distant clusters. Work on zero redshift, luminous far-IR galaxies, calibrated by starburst models, demonstrates the usefulness of this color system in isolating starburst from normal star-forming colors, and also demonstrates a strong correlation with far-IR c...

متن کاملGlobular Clusters in Dense Clusters of Galaxies
Deep imaging data from the Keck II telescope are employed to study the globular cluster (GC) populations in the cores of six rich Abell clusters. The sample includes A754, A1644, A2124, A2147, A2151, and A2152 and covers the redshift range z = 0.035–0.066. These clusters also span a range in morphology from spiral-rich, irregular systems to centrally concentrated cD clusters rich in early-type ...
متن کاملThe Luminosity Function of Field Galaxies in the CNOC1 Redshift Survey
We have computed the luminosity function for a sample of 389 eld galaxies from the Canadian Network for Observational Cosmology cluster redshift survey (CNOC1), over the redshift range z = 0:2 0:6. We nd Schechter parameters M r 5 log h = 20:8 0:4 and = 1:3 0:2 in rest-frame Gunn r, and M BAB 5 log h = 19:6 0:3 and = 0:9 0:2 in rest-frame BAB. We have also split our sample at the color of a red...
