Non-parametric strong lens inversion of Cl~0024+1654: illustrating the monopole degeneracy
J. Liesenborgs, S. De Rijcke, H. Dejonghe +1
The cluster lens Cl 0024+1654 is undoubtedly one of the most beautiful examples of strong gravitational lensing, providing five large images of a single source with well-resolved s…
A generalisation of the mass-sheet degeneracy producing ring-like artefacts in the lens mass distribution
J. Liesenborgs, S. De Rijcke, H. Dejonghe +1
The inversion of a gravitational lens system is, as is well known, plagued by the so-called mass-sheet degeneracy: one can always rescale the density distribution of the lens and a…
Non-parametric inversion of gravitational lensing systems with few images using a multi-objective genetic algorithm
J. Liesenborgs, S. De Rijcke, H. Dejonghe +1
Galaxies acting as gravitational lenses are surrounded by, at most, a handful of images. This apparent paucity of information forces one to make the best possible use of what infor…
A genetic algorithm for the non-parametric inversion of strong lensing systems
J. Liesenborgs, S. De Rijcke, H. Dejonghe
We present a non-parametric technique to infer the projected-mass distribution of a gravitational lens system with multiple strong-lensed images. The technique involves a dynamic g…
