Weak lensing study of low mass galaxy groups: implications for Omega_m

H. Hoekstra, M. Franx, K. Kuijken +8

We report on the first measurement of the average mass and mass-to-light ratio of galaxy groups by analysing the weak lensing signal induced by these systems. The groups, which hav…

The Evolution of Population Gradients in Galaxy Clusters: the Butcher-Oemler Effect and Cluster Infall

E. Ellingson, H. Lin, H. K. C. Yee +1

We present photometric and spectroscopic measurements of the galaxy populations in clusters from the CNOC1 sample of rich, X-ray luminous clusters at . A classical…

Galaxy Groups at Intermediate Redshift

R. G. Carlberg, H. K. C. Yee, S. L. Morris +5

Galaxy groups likely to be virialized are identified within the CNOC2 intermediate redshift galaxy survey using an iterative method. The number-velocity dispersion relation is in a…

Active Galactic Nuclei in the CNOC2 Field Galaxy Redshift Survey

Patrick B. Hall, H. K. C. Yee, Huan Lin +7

We present a sample of 47 confirmed and 14 candidate Active Galactic Nuclei (AGN) discovered in the Canadian Network for Observational Cosmology field galaxy redshift survey (CNOC2…
