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…
Study of the depletion effect in the cluster MS1008-1224
Christophe Mayen, Genevieve Soucail
We present a detailed study of the depletion effect (the radial manifestation of the magnification bias) in the cluster MS1008-1224. Following our results concerning the simulation…
Spectroscopic confirmation of a cluster of galaxies at z=1 in the field of the gravitational lens MG2016+112
G. Soucail, J. P. Kneib, A. O. Jaunsen +3
We present new optical data on the cluster AX J2019+1127 identified by the X-ray satellite ASCA at z\sim 1 (Hattori et al. 1997). The data suggest the presence of a high-redshift c…
