papaya2: 2D Irreducible Minkowski Tensor computation
Fabian M. Schaller, Jenny Wagner, Sebastian C. Kapfer
A common challenge in scientific and technical domains is the quantitative description of geometries and shapes, e.g. in the analysis of microscope imagery or astronomical observat…
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…
