A roadmap to cosmological parameter analysis with third-order shear statistics III: Efficient estimation of third-order shear correlation functions and an application to the KiDS-1000 data
Lucas Porth, Sven Heydenreich, Pierre Burger +2
Third-order lensing statistics contain a wealth of cosmological information that is not captured by second-order statistics. However, the computational effort for estimating such s…
KiDS-1000 cosmology: Combined second- and third-order shear statistics
Pierre A. Burger, Lucas Porth, Sven Heydenreich +9
This paper performs the first cosmological parameter analysis of the KiDS-1000 data with second- and third-order shear statistics. This work builds on a series of papers that descr…
What is the super-sample covariance? A fresh perspective for second-order shear statistics
Laila Linke, Pierre A. Burger, Sven Heydenreich +2
Cosmological analyses of second-order weak lensing statistics require precise and accurate covariance estimates. These covariances are impacted by two sometimes neglected terms: A…
Euclid Preparation. XXVIII. Forecasts for ten different higher-order weak lensing statistics
Euclid Collaboration, V. Ajani, M. Baldi +211
Recent cosmic shear studies have shown that higher-order statistics (HOS) developed by independent teams now outperform standard two-point estimators in terms of statistical precis…
