Density mapping with weak lensing and phase information

Autor: David Bacon, Rafal M. Szepietowski, Risa H. Wechsler, Peter Melchior, J. P. Dietrich, M. T. Busha

The available probes of the large scale structure in the Universe have distinct properties: galaxies are a high resolution but biased tracer of mass, while weak lensing avoids such biases but, due to low signal-to-noise ratio, has poor resolution. We
