AMICO galaxy clusters in KiDS-1000: Cosmological constraints and mass calibration from counts and weak lensing Open
Aims. We present the joint modelling of weak-lensing and count measurements of the galaxy clusters detected with the Adaptive Matched Identifier of Clustered Objects (AMICO) code, in the fourth data release of the Kilo Degree Survey (KiDS-…

AMICO galaxy clusters in KiDS-1000: cosmological constraints and mass calibration from counts and weak lensing Open
We present the joint modelling of weak-lensing and count measurements of the galaxy clusters detected with the AMICO code, in the fourth data release of the Kilo Degree Survey (KiDS-1000). The analysed sample comprises about 8000 clusters,…

Recent cosmic shear studies have shown that higher-order statistics (HOS) developed by independent teams now outperform standard two-point estimators in terms of statistical precision thanks to their sensitivity to the non-Gaussian feature…

Reconstruction of weak lensing mass maps for non-Gaussian studies in the celestial sphere Open
We present a novel method for reconstructing weak lensing mass or convergence maps as a probe to study non-Gaussianities in the cosmic density field. While previous surveys have relied on a flat-sky approximation, forthcoming Stage IV surv…

Euclid: Reconstruction of weak-lensing mass maps for non-Gaussianity studies Open
Weak lensing, which is the deflection of light by matter along the line of sight, has proven to be an efficient method for constraining models of structure formation and reveal the nature of dark energy. So far, most weak-lensing studies h…
