Extreme value statistics of the weak lensing convergence: 1. primordial non-Gaussianities
Federica Capranico, Angelos Fotios Kalovidouris, Bjoern Malte Schaefer
The subject of this paper is the investigation of inflationary non-Gaussianities of the local type with extreme value statistics of the weak lensing convergence kappa. Specifically…
On the validity of the Born approximation for weak cosmic flexions
Bjoern Malte Schaefer, Lavinia Heisenberg, Angelos Fotios Kalovidouris +1
Weak lensing calculations are often made under the assumption of the Born approximation, where the ray path is approximated as a straight radial line. In addition, lens-lens coupli…
Parameter estimation biases due to contributions from the Rees-Sciama effect to the integrated Sachs-Wolfe spectrum
Bjoern Malte Schaefer, Angelos Fotios Kalovidouris, Lavinia Heisenberg
The subject of this paper is an investigation of the nonlinear contributions to the spectrum of the integrated Sachs-Wolfe (iSW) effect. We derive the corrections to the iSW-auto s…
