Improved lensing reconstruction with a non-parametric code

Poster

Résumé : Based on the SLAP code (Sendra et al. 2005) we improve the lensing reconstruction of the mass in a galaxy cluster by integrating physical priors in the code that greatly help to increse the resolution of the solution and reduce the uncertainties. The new code is tested with simulated data (strong lensing) that mimics real data. We explore the improvements by comparing the solutions obtained with and without the new physical priors and discuss the limitations of the new code.
