Weak gravitational lensing by voids [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 1999
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 and cosmic variance are the main factors which limit in principle the detection of lensing by voids.

Baryons, neutrinos, feedback and weak gravitational lensing [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2015
(Abridged) The effect of baryonic feedback on the dark matter mass distribution is generally considered to be a nuisance to weak gravitational lensing. Measurements of cosmological parameters are affected as feedback alters the cosmic shear signal on angular scales smaller than a few arcminutes.

Weak Gravitational Lensing and Its Cosmological Applications [PDF]

open access: yesAnnual Review of Nuclear and Particle Science, 2008
Weak gravitational lensing is a unique probe of the dark side of the universe: It provides a direct way to map the distribution of dark matter around galaxies and clusters of galaxies as well as on cosmological scales. Furthermore, the measurement of the weak lensing–induced distortions of the shapes of distant galaxies is a potentially powerful probe

Current status of weak gravitational lensing

open access: yesNew Astronomy Reviews, 2002
Weak gravitational lensing of distant galaxies by foreground structures has proven to be a powerful tool to study the mass distribution in the universe. Nowadays, attention has shifted from clusters of galaxies to the statistical properties of the large scale structures and the halos of (field) galaxies. These applications have become feasible with the
