Weak gravitational lensing, the deflection of light by mass, is one of the best tools to
constrain the growth of cosmic structure with time and reveal the nature of dark energy. I …

Weak gravitational lensing of background galaxies provides a direct probe of the projected
matter distribution in and around galaxy clusters. Here, we present a self-contained …

Masses of clusters of galaxies from weak gravitational lensing analyses of ever larger
samples are increasingly used as the reference to which baryonic scaling relations are …

GalSim is a collaborative, open-source project aimed at providing an image simulation tool
of enduring benefit to the astronomical community. It provides a software library for …

We present two galaxy shape catalogues from the Dark Energy Survey Year 1 data set,
covering 1500 deg2 with a median redshift of 0.59. The catalogues cover two main fields …

We present and characterize the catalog of galaxy shape measurements that will be used for
cosmological weak lensing measurements in the Wide layer of the first year of the Hyper …

A likelihood-based method for measuring weak gravitational lensing shear in deep galaxy
surveys is described and applied to the Canada–France–Hawaii Telescope (CFHT) Lensing …

As the statistical power of galaxy weak lensing reaches per cent level precision, large,
realistic, and robust simulations are required to calibrate observational systematics …

We constrain the matter density Ωm and the amplitude of density fluctuations σ8 within the
ΛCDM cosmological model with shear peak statistics and angular convergence power …

We present results from a set of simulations designed to constrain the weak lensing shear
calibration for the Hyper Suprime-Cam (HSC) survey. These simulations include HSC …
