Abstract

The serendipitous discovery of a gravitational lens system formed by an elliptical galaxy at z ∼ 1 and a post-starburst galaxy at z ∼ 3.8 brings a unique opportunity to study in detail the mass profile of a massive and relaxed object at a look back time of half the age of the universe. We sketch here a comparison of different methods to reconstruct the mass of the lens, both parametrically and non-parametrically, highlighting their advantanges and limitations.
