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 …

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 …

Euclid is a mission of the European Space Agency that is designed to constrain the
properties of dark energy and gravity via weak gravitational lensing and galaxy clustering. It …

Likelihood-free inference provides a framework for performing rigorous Bayesian inference
using only forward simulations, properly accounting for all physical and observational effects …

We present weak lensing shear catalogues from the fourth data release of the Kilo-Degree
Survey, KiDS-1000, spanning 1006 square degrees of deep and high-resolution imaging …

Abstract The Kilo-Degree Survey (KiDS) is a multi-band imaging survey designed for
cosmological studies from weak lensing and photometric redshifts. It uses the European …

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 …

Abstract The Chinese Space Station Optical Survey (CSS-OS) is a planned full sky survey
operated by the Chinese Space Station Telescope (CSST). It can simultaneously perform …

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 …
