KiDS-Legacy: Covariance validation and the unified OneCovariance framework for projected large-scale structure observables
Robert Reischke, Sandra Unruh, Marika Asgari +24
We introduce OneCovariance, an open-source software designed to accurately compute covariance matrices for an arbitrary set of two-point summary statistics across a variety of larg…

KiDS-1000 and DES-Y1 combined: Cosmology from peak count statistics
Joachim Harnois-Deraps, Sven Heydenreich, Benjamin Giblin +10
We analyse the fourth data release of the Kilo Degree Survey (KiDS-1000) and extract cosmological parameter constraints based on the cosmic shear peak count statistics. Peaks are i…
