Generalised model-independent characterisation of strong gravitational lenses V: reconstructing the lensing distance ratio by supernovae for a general Friedmann universe
Jenny Wagner, Sven Meyer
We determine the cosmic expansion rate from supernovae of type Ia to set up a data-based distance measure that does not make assumptions about the constituents of the universe, i.e…

Multiply-imaged time-varying sources behind galaxy clusters - Comparing FRBs to QSOs, SNe, and GRBs
Jenny Wagner, Jori Liesenborgs, David Eichler
With upcoming (continuum) surveys of high-resolution radio telescopes, detection rates of fast radio bursts (FRBs) might approach per sky per day by future extremely large o…

Generalised model-independent characterisation of strong gravitational lenses IV: formalism-intrinsic degeneracies
Jenny Wagner
Based on the standard gravitational lensing formalism with its effective, projected lensing potential in a given background cosmology, we investigate under which transformations of…
