A Model of Habitability Within the Milky Way Galaxy

Michael G. Gowanlock, David R. Patton, Sabine M. McConnell

We present a model of the Galactic Habitable Zone (GHZ), described in terms of the spatial and temporal dimensions of the Galaxy that may favour the development of complex life. Th…

Environment and Galaxy Evolution at Intermediate Redshift in the CNOC2 Survey

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

(abridged) The systematic variation of galaxy colors and types with clustering environment could either be the result of local conditions at formation or subsequent environmental e…

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…

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…

Spectroscopic Gravitational Lens Candidates in the CNOC2 Field Galaxy Redshift Survey

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

We present five candidate gravitational lenses discovered spectroscopically in the Canadian Network for Observational Cosmology Field Galaxy Redshift Survey (CNOC2), along with one…
