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 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 of the CMB [PDF]
Phys.Rept. 429 (2006) 1-65, 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.

Image Simulations for Strong and Weak Gravitational Lensing [PDF]
Symmetry, 2020 Gravitational lensing has been identified as a powerful tool to address fundamental problems in astrophysics at different scales, ranging from exoplanet identification to dark energy and dark matter characterization in cosmology.

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 ...

The gravitational bending of acoustic Schwarzschild black hole [PDF]
European Physical Journal C: Particles and Fields, 2023 Acoustic black hole is becoming an attractive topic in recent years, for it open-up new direction for experimental/observational explorations of black holes.

Weak Gravitational Lensing [PDF]
Phys.Rept.340:291-472,2001, 1999 We review theory and applications of weak gravitational lensing. After summarising Friedmann-Lemaitre cosmological models, we present the formalism of gravitational lensing and light propagation in arbitrary space-times. We discuss how weak-lensing effects can be measured.

Weak gravitational lensing [PDF]
Proceedings of Frontiers of Fundamental Physics 14 — PoS(FFP14), 2008 In this brief review I consider the advances made in weak gravitational lensing over the last 8 years, concentrating on the large scales - cosmic shear.
