Cosmic shear is the distortion of images of distant galaxies due to weak gravitational lensing
by the large-scale structure in the Universe. Such images are coherently deformed by the …

Weak gravitational lensing is responsible for the shearing and magnification of the images of
high-redshift sources due to the presence of intervening matter. The distortions are due to …

It is common practice in cosmology to model large-scale structure observables as lognormal
random fields, and this approach has been successfully applied in the past to the matter …

It is generally assumed within the standard cosmological model that initial density
perturbations are Gaussian at all scales. However, primordial quantum diffusion …

Pinning down the total neutrino mass and the dark energy equation of state is a key aim for
upcoming galaxy surveys. Weak lensing is a unique probe of the total matter distribution …

We present 108 full-sky gravitational lensing simulation data sets generated by performing
multiple-lens plane ray-tracing through high-resolution cosmological N-body simulations …

Multiple images, microlensing (with appreciable magnifications) and arcs in clusters are
phenomena of strong lensing. In weak gravitational lensing, the Jacobi matrix A is very close …

Most cosmic shear analyses to date have relied on summary statistics (eg ξ+ and ξ−). These
types of analyses are necessarily suboptimal, as the use of summary statistics is lossy. In …

We perform high-resolution ray-tracing simulations to investigate probability distribution
functions (PDFs) of lensing convergence, shear, and magnification on distant sources up to …

Context. Accurate estimates of the errors on the cosmological parameters inferred from
cosmic shear surveys require accurate estimates of the covariance of the cosmic shear …
