Model-independent and model-based local lensing properties of CL0024+1654 from multiply-imaged galaxies
Jenny Wagner, Jori Liesenborgs, Nicolas Tessore
We investigate to which precision local magnification ratios, , ratios of convergences, , and reduced shears, , can be determined model-independ…
An unbiased estimator for the ellipticity from image moments
Nicolas Tessore
An unbiased estimator for the ellipticity of an object in a noisy image is given in terms of the image moments. Three assumptions are made: i) the pixel noise is normally distribut…
Generalised model-independent characterisation of strong gravitational lenses II: Transformation matrix between multiple images
Jenny Wagner, Nicolas Tessore
(shortened) We determine the transformation matrix T that maps multiple images with resolved features onto one another and that is based on a Taylor-expanded lensing potential clos…
Core or cusps: The central dark matter profile of a redshift one strong lensing cluster with a bright central image
Thomas E. Collett, Elizabeth Buckley-Geer, Huan Lin +58
We report on SPT-CLJ2011-5228, a giant system of arcs created by a cluster at . The arc system is notable for the presence of a bright central image. The source is a Lyman…
