void-lensing

This repository contains data and python code for the stacked weak-lensing measurement of cosmic voids in SDSS, as presented in the paper First measurement of gravitational lensing by cosmic voids in SDSS by Peter Melchior, P.M. Sutter, Erin S. Sheldon, Elisabeth Krause and Benjamin D. Wandelt: http://arxiv.org/abs/1309.2045

The file voids_rebinned.py provides a reasonably detailed example of the code capabilities, most importantly the calculation of the E/B-mode lensing profile around voids in predefined bins of r/R_v, including errors from bootstrap resampling.

You can’t perform that action at this time.
