The different Clustering of red and blue galaxies: a robust signal from w(theta)
Remi A. Cabanac, Valerie de Lapparent, P. Hickson
A sample of ~20,000 galaxies covering 0.76 deg2 were observed with the CFHT-UH8K up to V<23.5 and I<22.5. The angular correlation analysis of the red selected sample (V-I>1.4) show…
The Large Zenith Telescope: Redshifts and Physical Parameters of Faint Objects from a Principal Component Analysis
Remi A. Cabanac, Valerie de Lapparent
The future Large Zenith Telescope Survey will provide a catalog of spectrophotometric energy distributions (40 filters) of ~10^6 objects. In this paper, we shows that the principal…
The ESO-Sculptor Faint Galaxy Survey: Large-Scale Structure and Galaxy Populations at 0.1 < z < 0.5
V. de Lapparent, G. Galaz, S. Arnouts +2
We describe the current status of the ESO-Sculptor Survey. The observational goal has been to produce a new multi-color photometric catalogue of galaxies in a region located near t…
The ESO-Sculptor Survey: Spectral classification of galaxies with z < 0.5
Gaspar Galaz, Valerie de Lapparent
Using the ESO-Sculptor galaxy redshift survey data (ESS), we have extensively tested the Principal Components Analysis (PCA) method to perform the spectral classification of galaxi…
