The Evolution of Stellar Mass in the NICMOS UDF and the CFHTLS Deep Fields
Stephen Gwyn, F. D. A. Hartwick, Anudeep Kanwar +2
We measure the build-up of the stellar mass of galaxies from z=6 to z=1. Using 15 band multicolour imaging data in the NICMOS Ultra Deep Field we derive photometric redshifts and m…
Observations of Candidate z=1.54 Quasar Host Clusters
Patrick Hall, Marcin Sawicki, C. J. Pritchet +2
We present new data on several z=1.54 radio-loud quasar fields from a sample of 31 at z=1-2 in which we have previously identified an excess population of predominantly red galaxie…
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…
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…
The CNOC2 Field Galaxy Redshift Survey
H. K. C. Yee, M. J. Sawicki, R. G. Carlberg +8
This paper provides a brief description of the CNOC2 Redshift Survey being carried out at CFHT, giving the scope, technique, and current status of the survey, and some preliminary…
Omega baryon via Oort's Method
R. G. Carlberg, S. L. Morris, H. K. C. Yee +11
The baryon density of the universe is equal to the product of the baryon-to-light ratio, M_b/L, and the luminosity density, j. We estimate M_b/L as the sum of the masses of the X-r…
