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…
Cosmic Strings Lens Phenomenology Revisited
Francis Bernardeau, Jean-Philippe Uzan
We present investigations of lens phenomenological properties of cosmic strings for deep galaxy surveys. General results that have obtained for lineic energy distribution are prese…
Construction of the one-point PDF of the local aperture mass in weak lensing maps
F. Bernardeau, P. Valageas
We present a general method for the reconstruction of the one-point Probability Distribution Function of the local aperture mass in weak lensing maps. Exact results, that neglect t…
