Infrared observations of gravitational lensing in Abell 2219 with CIRSI
Meghan E. Gray, Richard S. Ellis, Alexandre Refregier +5
We present the first detection of a gravitational depletion signal at near-infrared wavelengths, based on deep panoramic images of the cluster Abell 2219 (z=0.22) taken with the Ca…
Strong and weak lensing analysis of cluster Abell 2219 based on optical and near infrared data
J. Bezecourt, H. Hoekstra, M. E. Gray +3
We present a gravitational lensing study of the massive galaxy cluster A2219 (redshift 0.22). This investigation is based on multicolour images from U through H, which allows photo…
Lensed galaxies in Abell 370 II. The ultraviolet properties of arclets and the star formation rate at high redshift
J. Bezecourt, G. Soucail, R. S. Ellis +1
We discuss the statistical properties of faint background galaxies detected in a deep Hubble Space Telescope ultraviolet (F336W) Wide Field Planetary Camera 2 image of the lensing…
A ring galaxy at z=1 lensed by the cluster Abell 370
G. Soucail, J. P. Kneib, J. Bezecourt +3
We present a study of a very peculiar object found in the field of the cluster-lens Abell 370. This object displays, in HST imaging, a spectacular morphology comparable to nearby r…
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…
Arcs statistics as a probe of galaxy evolution
J. Bezecourt
Number counts and redshift distribution of gravitational arcs are computed in the field of massive clusters of galaxies to probe the universe at high redshift. Using an accurate mo…
