Plasma lensing in comparison to gravitational lensing -- Formalism and degeneracies
Jenny Wagner, Xinzhong Er
Gravitational and plasma lensing share the same mathematical formalism in the limit of geometrical optics. Both phenomena can be effectively described by a projected, two-dimension…
Self-gravitating dark matter gets in shape
Jenny Wagner
In our current best cosmological model, the vast majority of matter in the Universe is dark, consisting of yet undetected, non-baryonic particles that do not interact electro-magne…
Extended lens reconstructions with Grale: exploiting time domain, substructural and weak-lensing information
Jori Liesenborgs, Liliya L. R. Williams, Jenny Wagner +1
The information about the mass density of galaxy clusters provided by the gravitational lens effect has inspired many inversion techniques. In this article, updates to the previous…
Cosmic structures from a mathematical perspective 1. Dark matter halo mass density profiles
Jenny Wagner
The shapes of individual self-gravitating structures of an ensemble of identical, collisionless particles have remained elusive for decades. In particular, a reason why mass densit…
Model-independent and model-based local lensing properties of B0128+437 from resolved quasar images
Jenny Wagner, Liliya L. R. Williams
The galaxy-scale gravitational lens B0128+437 generates a quadrupole-image configuration of a background quasar that shows milli-arcsecond-scale subcomponents in the multiple image…
A model-independent characterisation of strong gravitational lensing by observables
Jenny Wagner
When light from a distant source object, like a galaxy or a supernova, travels towards us, it is deflected by massive objects that lie on its path. When the mass density of the def…
