Cluster Mass Profiles from a Bayesian Analysis of Weak Lensing Distortion and Magnification Measurements: Applications to Subaru Data
Keiichi Umetsu, Tom Broadhurst, Adi Zitrin +2
We directly construct model-independent mass profiles of galaxy clusters from combined weak-lensing distortion and magnification measurements within a Bayesian statistical framewor…

Full Lensing Analysis of Abell 1703: Comparison of Independent Lens-Modelling Techniques
Adi Zitrin, Tom Broadhurst, Keiichi Umetsu +10
The inner mass-profile of the relaxed cluster Abell 1703 is analysed by two very different strong-lensing techniques applied to deep ACS and WFC3 imaging. Our parametric method has…
