V- and I-band observations of the halo of NGC 5907
J. Lequeux, B. Fort, M. Dantel-Fort Fort +2
Using long exposures taken in the V and I bands with a 40964096 pixel CCD array at the prime focus of the Canada-France-Hawaii telescope, we have confirmed the discovery by…
A radial mass profile analysis of the lensing cluster MS2137-23
R. Gavazzi, B. Fort, Y. Mellier +2
We reanalyze the strong lens modeling of the cluster of galaxies MS2137-23 using a new data set obtained with the ESO VLT. We found the photometric redshifts of the two main arc sy…
Combining Strong and Weak Gravitational Lensing in Abell 1689
M. Limousin, J. Richard, E. Jullo +14
We present a reconstruction of the mass distribution of galaxy cluster Abell 1689 at z = 0.18 using detected strong lensing features from deep HST/ACS observations and extensive gr…
Weak lensing analysis of MS 1008-1224 with the VLT
R. Athreya, Y. Mellier, L. Van Waerbeke +3
We present a gravitational lensing analysis of the cluster of galaxies MS 1008-1224 (z=0.30), based on very deep observations obtained using the VLT with FORS and ISAAC during the…
An ISOCAM survey through gravitationally lensing galaxy clusters. IV. Luminous infrared galaxies in Cl 0024+1654 and the dynamical status of clusters
D. Coia, B. McBreen, L. Metcalfe +9
Observations of the core of the massive cluster Cl 0024+1654, at a redshift z=0.39, were obtained with the Infrared Space Observatory using ISOCAM at 6.7 mum and 14.3 mum (hereafte…
Detection of shear due to weak lensing by large-scale structure
P. Schneider, L. van Waerbeke, Y. Mellier +3
We present evidence for a coherent shear signal in a field containing the z=1.2 radio-source PKS1508-05. Since there were no intervening mass concentrations known before targeting…
