Euclid preparation. LXXXV. Toward a DR1 application of higher-order weak lensing statistics
Euclid Collaboration, S. Vinciguerra, F. Bouchè +284
This is the second paper in the HOWLS (higher-order weak lensing statistics) series exploring the usage of non-Gaussian statistics for cosmology inference within Euclid. With respe…

Generative modeling of convergence maps based on predicted one-point statistics
Vilasini Tinnaneri Sreekanth, Jean-Luc Starck, Sandrine Codis
Context: Weak gravitational lensing is a key cosmological probe for current and future large-scale surveys. While power spectra are commonly used for analyses, they fail to capture…

Theoretical wavelet -norm from one-point PDF prediction
Vilasini Tinnaneri Sreekanth, Sandrine Codis, Alexandre Barthelemy +1
Weak gravitational lensing, resulting from the bending of light due to the presence of matter along the line of sight, is a potent tool for exploring large-scale structures, partic…
