15 Sep 1999 | | Subject: | astro-ph | | Affiliation: | Oxford, UK), Liliya L.R. Williams (UVic, Canada), Hanadi AbdelSalam (Groningen | | Abstract: | The lensing information provided by multiple images, arclets, and statistical distortions can all be formulated as linear constraints on the arrival-time surface, and hence on the mass distribution. This reduces cluster lens reconstruction from combined strong and weak lensing to a standard type of inversion problem. Moreover, the mass sheet degeneracy is broken if there are sources at different redshifts. | | Source: | arXiv, astro-ph/9909249 | | Services: | Forum | Review | PDF | Favorites | |
