Multiple-Images in the Cluster Lens Abell 2218: Constraining the Geometry of the Universe ?
G. Soucail, J. P. Kneib, G. Golse
In this Letter we present a detailed study of the lensing configuration in the cluster Abell 2218. Four multiple-images systems with measured spectroscopic redshifts have been iden…
Constraints on (Omega_M0, Omega_Lambda) from strong lensing in AC 114
G. Golse, J. -P. Kneib, G. Soucail
We use a strong lensing inversion in the cluster of galaxies AC 114 to derive constraints on the cosmological parameters Omega_M0 and Omega_Lambda. If it is possible to measure spe…
Exploring the gravitationally lensed system HE1104-1805: VLT spectroscopy of the lens at z=0.729
C. Lidman, F. Courbin, J. -P. Kneib +3
Using FORS2, mounted on Kueyen (UT2 of the VLT), we have obtained the redshift of the lensing galaxy in the gravitational lens system HE1104-1805. We measure z=0.729, in good agree…
Constraining the cosmological parameters from gravitational lenses with several families of images
G. Golse, J. -P. Kneib, G. Soucail
The knowledge of the redshift of multiple images in cluster-lenses allows to determine precisely the total projected mass within the Einstein radius. The observation of various mul…
Constraining (Ω_m,Ω_λ) from strong lensing
G. Golse, J. -P. Kneib, G. Soucail
The knowledge of the redshift of multiple images in cluster-lenses allows to determine precisely the total projected mass within the Einstein radius. The observation of various mul…
