The comoving luminosity density of the Universe is estimated from the CFRS faint galaxy sample in three wavebands (2800A, 4400A and 1 micron) over the redshift range 0 < z < 1. In all three...
The Canada France Redshift Survey VIII: Evolution of the clustering of galaxies from z~1 (1995)
Fevre, O. Le, Hudon, D., Lilly, S. J., Crampton, D., Hammer, F., Tresse, L.
We have used the projected two-point correlation function, $w(r_p)$, to investigate the spatial distribution of the 591 galaxies with secure redshifts between $0 \leq z \leq 1.3$ in the five CFRS...

Schade, David, Crampton, David, Hammer, F., Fevre, O. Le, Lilly, S. J.
Six objects with broad emission lines and redshifts from 0.48 to 2.07 were discovered among 736 extragalactic objects in the Canada-France Redshift Survey (CFRS). Although the luminosities of half of...
The CANADA-FRANCE REDSHIFT SURVEY VI: Evolution of the galaxy luminosity function to z ~ 1 (1995)
Lilly, S. J., Tresse, L., Hammer, F., Crampton, David, Fevre, O. Le
The cosmic evolution of the field galaxy population has been studied out to a redshift of z ~ 1 using a sample of 730 I-band selected galaxies, of which 591 have secure redshifts with median ~ 0.56....
THE CANADA-FRANCE REDSHIFT SURVEY IX: HST Imaging of High-Redshift Field Galaxies (1995)
Schade, D. J., Lilly, S. J., Crampton, David, Hammer, F., Fevre, O. Le, Tresse, L.
HST B and I images are presented of 32 CFRS galaxies with secure redshifts in the range 0.5 < z < 1.2. These galaxies exhibit the same range of morphological types as seen locally, i.e., ellipticals,...
Lilly, S. J., Fevre, O. Le, Crampton, David, Hammer, F., Tresse, L.
The Canada-France Redshift Survey has been undertaken to provide a large well-defined sample of faint galaxies at high redshift in which the selection criteria match as closely as possible those of...
Fevre, O. Le, Crampton, David, Lilly, S. J., Hammer, F., Tresse, L.
This paper describes the methods used to obtain the spectroscopic data and construct redshift catalogs for the Canada-France deep Redshift Survey (CFRS). The full data set consists of more than one...
Lilly, S. J., Hammer, F., Fevre, O. Le, Crampton, David
This paper is one of a series describing the Canada-France Redshift Survey (CFRS). It is shown how the shape of the continuum around the emission line can be used to distinguish between [OII] 3727 at...
Hammer, F., Crampton, David, Fevre, O. Le, Lilly, S. J.
Possible surface brightness selection effects in the redshift catalogs of the Canada-France Redshift Survey are investigated through comparisons of subsamples of the data. Our analyses demonstrate...
THE CANADA-FRANCE REDSHIFT SURVEY V: Global Properties of the Sample (1995)
Crampton, David, Fevre, O. Le, Lilly, S. J., Hammer, F.
The photometric and spectroscopic data of the CFRS survey of objects with 17.5 < I_{AB} < 22.5 are combined and analysed. The overall completeness is 85%. The redshift histogram of the sample is...
The Canada-France Redshift Survey VII: Optical counterparts of microJansky radiosources (1995)
Hammer, F., Crampton, D., Fevre, O. Le, Lilly, S., Kenet, T.
Deep imaging and spectroscopy have been carried out for optical counterparts of a complete sample of S$>$16 $\mu$Jy radiosources during the course of the Canada-France Redshift Survey (CFRS). All 36...
Nature of Field Galaxies in the (z (1994)
Tresse, L., Rola, C., Hammer, F., Stasinska, G.
We present the first detailed spectroscopic study of field galaxies up to z=0.3 from the I-magnitude limited CFRS sample. In this complete sample, we find that about half of the objects are blue...
