Weak Lensing

چکیده
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 lensing.

Weak gravitational lensing
We review theory and applications of weak gravitational lensing. After summarising Friedmann}Lemam( tre cosmological models, we present the formalism of gravitational lensing and light propagation in arbitrary space}times. We discuss how weak-lensing e!ects can be measured. The formalism is then applied to reconstructions of galaxy-cluster mass distributions, gravitational lensing by large-scal...
متن کاملCombined reconstruction of weak and strong lensing data with WSLAP
We describe a method to estimate the mass distribution of a gravitational lens and the position of the sources from combined strong and weak lensing data. The algorithm combines weak and strong lensing data in a unified way producing a solution which is valid in both the weak and strong lensing regimes. We study how the result depends on the relative weighting of the weak and strong lensing dat...
متن کاملSimulating Weak Lensing by Large Scale Structure
We model weak gravitational lensing of light by large-scale structure using ray tracing through N-body simulations. The method is described with particular attention paid to numerical convergence. We investigate some of the key approximations in the multi-plane ray tracing algorithm. Our simulated shear and convergence maps are used to explore how well standard assumptions about weak lensing ho...

We present two weak lensing reconstructions of the nearby (zcl = 0.055) merging cluster Abell 3667, based on observations taken ∼ 1 year apart under different seeing conditions. This is the lowest redshift cluster with a weak lensing mass reconstruction to date. The reproducibility of features in the two mass maps demonstrate that weak lensing studies of low-redshift clusters are feasible. Thes...
متن کاملA New Method for measuring Weak Gravitational Lensing Shear using Higher Order Spin-2 HOLICs
We investigate the possibility to use higher order moments of gravitational lensed images in the weak lensing analysis. For this purpose we employ spin-2 component of HOLICs(Higher Order Lensing Characteristics) developed by us. We test the weak lensing analysis with spin-2 HOLICs using actual, ground based Subaru observations of the massive galaxy cluster A1689(z=0.183). It turns out that spin...
