Photometric Redshifts in lensing clusters: Identification and Calibration of faint high-z galaxies
Roser Pello, Jean-Paul Kneib, Micol Bolzonella +1
We discuss a method aiming to use photometric redshifts in lensing clusters to access the population of distant background sources. The amplification provided by gravitational lens…
Two multiple-imaged z=4.05 galaxies in the cluster-lens Abell 2390
R. Pello, J. -P. Kneib, J. -F. Le Borgne +8
We present the first results on the identification and study of very distant field galaxies in the core of cluster-lenses, using a selection criterium based on both lens modelling…
High-Redshift Clustering in the HDF
J. M. Miralles, R. Pello
This paper addresses the problem of detecting high-redshift clustering in deep photometric surveys. We have used photometric redshifts to select different samples of galaxies in th…
An optical and near-IR survey of nearby clusters of galaxies
S. Andreon, J. Annis, J. -C. Cuillandre +6
We present an optical and near-infrared survey of galaxies in nearby clusters aimed at determining fundamental quantities of galaxies, such as multivariate luminosity function and…
Identification of a high redshift cluster in the field of Q2345+007 through deep BRIJK' photometry
R. Pello, J. M. Miralles, J. -F. Le Borgne +3
This paper describes new results on the identification of the complex gravita- tional lens responsible for the double quasar Q2345+007. A gravitational shear field was detected rec…
