[170.10] A Multi-Resolution Weak Lensing Reconstruction Method

H. Khiabanian, I.P. Dell'Antonio (Brown University)

We present an entropy-regularized maximum-likelihood method for reconstructing two dimensional mass maps using weak gravitational lensing data. This inverse method can produce a single mass map with multiple resolutions in different parts of the observed field. It can also incorporate both photometric and spectroscopic redshift information in order to reconstruct mass maps with higher accuracy. We apply our method to one of the fields of the Deep Lens Survey, a deep (R < 26) multi-color survey of five separate 4 square degree patches of sky and compare the results to the direct methods of projected mass reconstruction.
