Mass-detection of a matter concentration projected near the cluster Abell 1942: Dark clump or high-redshift cluster?
T. Erben, L. van Waerbeke, Y. Mellier +4
A weak-lensing analysis of wide-field - and -band images centered on the cluster Abell 1942 has uncovered a mass concentration arcminutes South of the cluster center…

NGC 5907 revisited: a stellar halo formed by cannibalism?
J. Lequeux, F. Combes, M. Dantel-Fort +3
We report on further observations of the luminous halo of NGC 5907. New V, I and B deep photometry confirms the existence of an extended stellar halo redder than the disk. Our data…

Detection of Weak Lensing in the Fields of Luminous Radiosources
B. Fort, Y. Mellier, M. Dantel-Fort +2
We present a first attempt to reveal the possible existence of large foreground mass condensations directly responsible for the gravitational magnification of four distant luminous…
