Maximum-Entropy Reconstruction of the Distribution of Mass in Cluster MS1054-03 from Weak Lensing Data

Abstract

Weak gravitational lensing studies of clusters of galaxies provide complimentary information to that from X-ray data; the measured signal depends only on the cluster's projected mass, independent of dynamical assumptions. Here we apply a maximum-entropy method algorithm for reconstructing the two-dimensional density distribution to two sets of shear data for the high redshift cluster MS1054-03, courtesy of Clowe et al (2000) and Hoekstra et al (2000).
