DarkMappy: Mapping the dark universe

Web Github

DarkMappy is a lightweight python package which implements hybrid Bayesian dark-matter reconstruction techniques on the plane and on the celestial sphere. For comparison (and as initialisation for our iterations) the spherical Kaiser-Squires estimator is also implemented. These techniques are based on maximum a posteriori estimation which, by construction, support principled uncertainty quantification.
