First weak lensing results from the Red-Sequence Cluster Survey
The Red-Sequence Cluster Survey (RCS) is a 100 deg galaxy cluster survey designed to provide a large sample of optically selected clusters of galaxies with redshifts 0.1 < z < 1.4. The survey data are also useful for a variety of lensing studies. Several strong lensing clusters have been discovered so far, and follow up observations are underway. In these proceedings we present some of the firs...
متن کاملWeak Lensing from Strong Clustering
We investigate the effect of weak gravitational lensing in the limit of small angular scales where projected galaxy clustering is strongly nonlinear. This is the regime likely to be probed by future weak lensing surveys. We use well-motivated hierarchical scaling arguments and the plane-parallel approximation to study multi-point statistical properties of the convergence field. These statistics...
متن کاملWeak Lensing
In the preceding chapters, the effects of lensing were so strong as to leave an unmistakable imprint on a specific source, allowing a detailed treatment. However, only the densest regions of the universe are able to provide such a spectacular lensing effect. To study more representative regions of the universe, we must examine large numbers of sources statistically. This is the domain of weak l...
متن کاملCosmological Constraints from Weak Lensing Surveys
Focusing on the well motivated aperture mass statistics Map, we study the possibility of constraining cosmological parameters using future space based SNAP class weak lensing missions. Using completely analytical results we construct the covariance matrix for estimators based on two-point and three-point statistics. Our approach incorporates an accurate modelling of higher-order statistics to d...
متن کاملCluster Mass Profiles from Weak Lensing II
When a cluster gravitationally lenses faint background galaxies, its tidal gravitational field distorts their shapes (shear effect) and its magnification effect changes the observed number density. In Schneider, King & Erben (2000) we developed likelihood techniques to compare the constraints on cluster mass profiles that can be obtained using the shear and magnification information. This work ...
