Two-dimensional weak lensing shear for cluster mass, concentration, ellipticity and miscentering estimation
Calum Murray, Martin Kilbinger, Constantin Payerne
The effects of weak gravitational lensing induced by clusters of galaxies makes it possible to constrain their dark matter distribution. In general mass estimates from weak lensing…
Mitigating baryonic effects in weak lensing with higher-order statistics
Andreas Tersenov, Sacha Guerrini, Jean-Luc Starck +1
Weak gravitational lensing is a premier cosmological probe, but its small-scale statistical power is compromised by baryonic feedback. Higher-order statistics capture non-Gaussian…
Assessing the large-scale angular clustering of UNIONS Lyman Break Galaxies via cross-correlations
Constantin Payerne, Christophe Yèche, William d'Assignies Doumerg +8
Lyman-break galaxies (LBGs), selected via the strong spectral break blueward of the Lyman limit, are powerful tracers of large-scale structure at redshifts . In this work, we…
Measuring satellite galaxy subhalo masses in redMaPPer clusters with UNIONS weak lensing data
Roman Akhmetshyn, Jack Elvin-Poole, Michael J. Hudson +13
In this work, we present the observed galaxy-galaxy lensing signal of satellite galaxies in rich clusters obtained from the Ultraviolet Near-Infrared Optical Northern Survey (UNION…
