UNIONS: a direct measurement of intrinsic alignment with BOSS/eBOSS spectroscopy
Fabian Hervas Peters, Martin Kilbinger, Romain Paviot +12
During their formation, galaxies are subject to tidal forces, which create correlations between their shapes and the large-scale structure of the Universe, known as intrinsic align…
Euclid preparation: Determining the weak lensing mass accuracy and precision for galaxy clusters
Euclid Collaboration, L. Ingoglia, M. Sereno +279
We investigate the level of accuracy and precision of cluster weak-lensing (WL) masses measured with the \Euclid data processing pipeline. We use the DEMNUni-Cov -body simulatio…
Point-Spread Function errors for weak lensing - density cross-correlations. Application to UNIONS
Ziwen Zhang, Martin Kilbinger, Fabian Hervas Peters +8
Aims:Calibrating the point spread function (PSF) is a fundamental part of weak gravitational lensing analyses. Even with corrected galaxy images, imperfect calibrations can introdu…
Euclid. I. Overview of the Euclid mission
Euclid Collaboration, Y. Mellier, Abdurro'uf +1134
The current standard model of cosmology successfully describes a variety of measurements, but the nature of its main ingredients, dark matter and dark energy, remains unknown. Eucl…
Euclid preparation. XLII. A unified catalogue-level reanalysis of weak lensing by galaxy clusters in five imaging surveys
Euclid Collaboration, M. Sereno, S. Farrens +221
Precise and accurate mass calibration is required to exploit galaxy clusters as astrophysical and cosmological probes in the Euclid era. Systematic errors in lensing signals by gal…
Black-Hole-to-Halo Mass Relation From UNIONS Weak Lensing
Qinxun Li, Martin Kilbinger, Wentao Luo +17
This letter presents, for the first time, direct constraints on the black-hole-to-halo-mass relation using weak gravitational lensing measurements. We construct type I and type II…
