A roadmap to cosmological parameter analysis with third-order shear statistics IV. Analytic cross-covariance between second- and third-order aperture masses

Niek Wielders, Laila Linke, Pierre A. Burger +3

Weak gravitational lensing is a powerful probe of cosmology, with second-order shear statistics commonly used to constrain parameters such as the matter density $\hat{I}{\text{c◯}}_{\mathrm{m}}$ and…
