Cosmic Shear and Clusters of Galaxies
Y. Mellier, L. van Waerbeke, T. Erben +9
The first detections of cosmic shear signal reported recently by 4 independent groups cover angular scales between one and 10 arcmin. On those scales, the cosmic shear is a signatu…
A Numerical Study of Cosmic Shear Statistics
A. Thion, Y. Mellier, F. Bernardeau +3
We explore the stability of the variance and skewness of the cosmic gravitational convergence field, using two different approaches: first we simulate a whole MEGACAM survey (100 s…
Cosmic Shear with the VLT
R. Maoli, Y. Mellier, L. van Waerbeke +5
We report on the detection of cosmic shear on angular scales of 1.3-6.5 arcmin using 45 independent empty fields observed with the Very Large Telescope (VLT). This result confirms…
Cosmic Shear with the CFHT
L. van Waerbeke, Y. Mellier, T. Erben +10
We present results of our cosmic shear survey in progress at the Canada- France-Hawaii Telescope (CFHT). We analysed 1.7 sq. degrees of data, out of which we measured a significant…
Spectroscopic follow up of arclets in AC114 with the VLT
J. F. Le Borgne, L. Campusano, R. Pello +5
We present the first results on the VLT/FORS-1 spectroscopic survey of amplified sources and multiple images in the lensing cluster AC114. Background sources were selected in the c…
Photometric Redshifts and Gravitational Telescopes
R. Pello, M. Bolzonella, J. F. Le Borgne +8
We review the use of photometric redshifts in the particular context of Gravitational Telescopes. We discuss on the possible application of such a technique to the study of both th…
