Optimal cosmology from gravitational lensing: utilising the magnification and shear signals
2015Gravitational lensing studies the distortions of a distant galaxy’s observed size, shape or flux due to the tidal bending of photons by matter between the source and observer. Such distortions can be used to infer knowledge on the mass distribution of the intervening matter, such as the dark matter halos in which clusters of individual galaxies may ...

We demonstrate that topological voids in Regge calculus produce quantitative gravita-tional lensing signals with a unique, falsifiable prediction: an annular convergence ring atthe toroidal void major radius (Rmaj ≈ 100 kpc) that no spherically symmetric dark mat-ter model can produce.
