Mitigating Nonlinear Systematics in Weak Lensing Surveys II: Stability and Diagnostics with Intrinsic Alignment
Shiming Gu, Ludovic van Waerbeke, Francis Bernardeau +1
The Bernardeau-Nishimichi-Taruya (BNT) transform provides a powerful framework for analysing tomographic cosmic shear data by improving the localization of shear correlations in ph…
Cluster properties as a function of dynamical state in the DESI Legacy x UNIONS surveys
Syeda Lammim Ahad, Rashaad Reid, Charlie T. Mpetha +10
We investigate how the dynamical state of galaxy clusters influences their galaxy populations and mass distributions. Using photometrically selected clusters from the DESI Legacy I…
Unified weak lensing constraints on the evolution of the mass -- X-ray luminosity relation for galaxy clusters
Isabel Pederneiras, Alexis Finoguenov, Eduardo Cypriano +4
Scaling relations between galaxy cluster properties are crucial for understanding cosmology and baryonic physics. Rigorous calibration of the relation, employing weak lensi…
Cosmology from UNIONS weak lensing profiles of galaxy clusters
Charlie T. Mpetha, James E. Taylor, Yuba Amoura +12
Cosmological information is encoded in the structure of galaxy clusters. In Universes with less matter and larger initial density perturbations, clusters form earlier and have more…
Mitigating Nonlinear Systematics in Weak Lensing Surveys: The Bernardeau-Nishimichi-Taruya Approach
Shiming Gu, Ludovic van Waerbeke, Francis Bernardeau +1
Weak lensing surveys, along with most other late-Universe probes, have consistently measured a lower amplitude of the matter fluctuation spectrum, denoted by the parameter , c…
A hydrodynamical halo model for weak-lensing cross correlations
A. J. Mead, T. Tröster, C. Heymans +2
On the scale of galactic haloes, the distribution of matter in the cosmos is affected by energetic, non-gravitational processes; so-called baryonic feedback. A lack of knowledge ab…
