Shape, shear and flexion II - Quantifying the flexion formalism for extended sources with the ray-bundle method
Christopher J. Fluke, Paul D. Lasky
Flexion-based weak gravitational lensing analysis is proving to be a useful adjunct to traditional shear-based techniques. As flexion arises from gradients across an image, analyti…

Shape, shear & flexion: An analytic flexion formalism for realistic mass profiles
Paul Lasky, Chris Fluke
Flexion is a non-linear gravitational lensing effect that arises from gradients in the convergence and shear across an image. We derive a formalism that describes non-linear gravit…
