Weak gravitational lensing with DEIMOS [PDF]
Monthly Notices of the Royal Astronomical Society, 2011 We introduce a novel method for weak-lensing measurements, which is based on a mathematically exact deconvolution of the moments of the apparent brightness distribution of galaxies from the telescope's PSF.

Weak Gravitational Lensing by Voids [PDF]
Monthly Notices of the Royal Astronomical Society, 1998 We consider the prospects for detecting weak gravitational lensing by underdensities (voids) in the large-scale matter distribution. We derive the basic expressions for magnification and distortion by spherical voids. Clustering of the background sources

Weak gravitational lensing of finite beams [PDF]
Physical Review Letters, 2017 The standard theory of weak gravitational lensing relies on the infinitesimal light beam approximation. In this context, images are distorted by convergence and shear, the respective sources of which unphysically depend on the resolution of the ...

Weak Gravitational Lensing by Dark Clusters [PDF]
Monthly Notices of the Royal Astronomical Society, 2002 We calculate the abundance of dark-matter concentrations that are sufficiently overdense to produce a detectable weak-gravitational-lensing signal. Most of these overdensities are virialized halos containing identifiable X-ray and/or optical clusters ...

Weak Gravitational Lensing in Fourth Order Gravity [PDF]
Physical Review D, 2011 For a general class of analytic $f(R,R_{\alpha\beta}R^{\alpha\beta},R_{\alpha\beta\gamma\delta}R^{\alpha\beta\gamma\delta})$ we discuss the gravitational lensing in the Newtonian Limit of theory.

Weak gravitational lensing of the CMB [PDF]
Physics Reports, 2006 Weak gravitational lensing has several important effects on the cosmic microwave background (CMB): it changes the CMB power spectra, induces non-Gaussianities, and generates a B-mode polarization signal that is an important source of confusion for the signal from primordial gravitational waves.
