A plug-and-play approach with fast uncertainty quantification for weak lensing mass mapping
Hubert Leterme, Andreas Tersenov, Jalal Fadili +1
The paper presents PnPMass, a plug‑and‑play algorithm that reconstructs dark‑matter maps from weak‑lensing shear data using a single deep‑learning denoiser combined with gradient d…

UNIONS-3500 Weak Lensing: I. A Galaxy Shape Catalogue in the Northern Sky
F. Hervas-Peters, S. Guerrini, M. Kilbinger +15
Weak gravitational lensing has become a widely used effect to characterise the dark-matter distribution on large scales in the Universe by measuring galaxy ellipticities and their…

Impact of weak-lensing mass-mapping algorithms on cosmology inference
Andreas Tersenov, Lucie Baumont, Jean-Luc Starck +1
Weak-lensing mass-mapping algorithms, which reconstruct the convergence field from galaxy shear measurements, are crucial for extracting higher-order statistics to constrain cosmol…
