Cosmic Shear Review
L. Van Waerbeke, I. Tereno, Y. Mellier +1
We present an overview of the cosmic shear results obtained so far. We focus on the 2-point statistics only. Evidences supporting the cosmological origin of the measured signal are…
Cosmic Shear: The Dark Side of the Universe
L. Van Waerbeke, Y. Mellier, I. Tereno
We discuss the present status and future prospects for cosmic shear observations and their cosmological constraints. We review the evidences supporting the cosmological origin of t…
Tracing Matter with Weak Lensing Surveys
Y. Mellier, L. van Waerbeke
Gravitational weak lensing maps the location of (dark) matter at all scales. The lens-induced distortion field traces gravity fields and can be used to reconstruct the mass distrib…
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…
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…
