A roadmap to cosmological parameter analysis with third-order shear statistics II: Analytic covariance estimate
Laila Linke, Sven Heydenreich, Pierre A. Burger +1
Third-order weak lensing statistics are a promising tool for cosmological analyses since they extract cosmological information in the non-Gaussianity of the cosmic large-scale stru…
A roadmap to cosmological parameter analysis with third-order shear statistics I: Modelling and validation
Sven Heydenreich, Laila Linke, Pierre Burger +1
In this work, which is the first of a series to prepare a cosmological parameter analysis with third-order cosmic shear statistics, we model both the shear three-point correlation…
Persistent homology in cosmic shear II: A tomographic analysis of DES-Y1
Sven Heydenreich, Benjamin Brück, Pierre Burger +5
We demonstrate how to use persistent homology for cosmological parameter inference in a tomographic cosmic shear survey. We obtain the first cosmological parameter constraints from…
