Welcome to the turboGL website!




turboGL is a fast Mathematica code based on the stochastic approach to cumulative weak lensing (the sGL method) introduced in Ref. [1] and extended/revised in Ref. [4]. turboGL can easily compute the lensing PDF relative to arbitrary halo mass distributions, selection biases, number of observations, halo profiles and evolutions. Check the version history for the features included in the current version. If you want to be informed of a new version, please send an email. Do not hesitate to contact me if you have any questions or suggestions.
