Prospects for weak lensing/cosmic shear with VLTs
Y. Mellier, L. van Waerbeke, E. Bertin +4
The present status of weak lensing analyses of clusters of galaxies and of cosmic shear surveys are presented and discussed. We focus on the impact of very large telescopes on pres…
Cosmological Weak Lensing
Y. Mellier, L. van Waerbeke, F. Bernardeau +1
We present the current status of cosmic shear studies and their implications on cosmological models. Theoretical expectations and observational results are discussed in the framewo…
Analysis of two-point statistics of cosmic shear: I. Estimators and covariances
Peter Schneider, Ludovic van Waerbeke, Martin Kilbinger +1
We derive in this paper expressions for the covariance matrix of the cosmic shear two-point correlation functions which are readily applied to any survey geometry. Furthermore, we…
Weak lensing study of galaxy biasing
Henk Hoekstra, Ludo van Waerbeke, Michael D. Gladders +2
We combine weak lensing measurements from the Red-Sequence Cluster Survey and the VIRMOS-DESCART survey, and present the first direct measurements of the bias parameter b and the g…
Detection of non-Gaussian Signatures in the VIRMOS-DESCART Lensing Survey
F. Bernardeau, Y. Mellier, L. van Waerbeke
We have detected non-Gaussian signatures in the VIRMOS-DESCART weak lensing survey from a measurement of the three-point shear correlation function, following the method developed…
Patterns in the weak shear 3-point correlation function
F. Bernardeau, L. van Waerbeke, Y. Mellier
We explore the scale and angular dependence of the cosmic shear three-point correlation function. The shear field is found to have a much more complex three-point function than the…
