Model-independent and model-based local lensing properties of CL0024+1654 from multiply-imaged galaxies
Jenny Wagner, Jori Liesenborgs, Nicolas Tessore
We investigate to which precision local magnification ratios, , ratios of convergences, , and reduced shears, , can be determined model-independ…

Generalised model-independent characterisation of strong gravitational lenses III: perturbed axisymmetric lenses
Jenny Wagner
In galaxy-galaxy strong gravitational lensing, Einstein rings are generated when the lensing galaxy has an axisymmetric lensing potential and the source galaxy is aligned with its…

Generalised model-independent characterisation of strong gravitational lenses II: Transformation matrix between multiple images
Jenny Wagner, Nicolas Tessore
(shortened) We determine the transformation matrix T that maps multiple images with resolved features onto one another and that is based on a Taylor-expanded lensing potential clos…
