Degeneracies of parametric lens model families near folds and cusps
Jenny Wagner, Matthias Bartelmann
We develop an approach to select families of lens models that can describe doubly and triply gravitationally lensed images near folds and cusps using the model-independent ratios o…

Model-independent characterisation of strong gravitational lenses
Jenny Wagner, Matthias Bartelmann
We develop a new approach to extracting model-independent information from observations of strong gravitational lenses. The approach is based on the generic properties of images ne…
