Sub-L* Galaxies at Redshifts z~4, 3, and 2: Their UV Luminosity Function and Luminosity Density

Marcin Sawicki, David Thompson

We use very deep (R_lim=27) UGRI imaging to study the evolution of the faint end of the UV-selected galaxy luminosity function from z~4 to z~2. We find that the luminosity function…

Galaxy Clustering in the CNOC2 Redshift Survey

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

The correlation evolution of a high luminosity subsample of the CNOC2 redshift survey is examined. The sample is restricted to galaxies for which the k corrected and evolution corr…

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 DDO IVC Distance Project

Michael D. Gladders, Tracy E. Clarke, Christopher R. Burns +14

We present the first set of distance limits from the David Dunlap Observatory Intermediate Velocity Cloud (DDO IVC) distance project. Such distance measures are crucial to understa…

The David Dunlap Observatory IVC Distance Project: First Results

T. E. Clarke, Gabriela Mallen-Ornelas, Marcin Sawicki +5

We present distance estimates to a set of high-latitude intermediate-velocity HI clouds. We explore some of the physical parameters that can be determined from these results, such…

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…
