Welcome to the Pangloss Wiki!

The goal of the Pangloss project is to model and understand massive structures in the Universe, given photometric and gravitational lensing information about galaxies in wide field surveys. The original motivation was to be able to account for objects along the line of sight to various interesting targets, whose apparent position, brightness and shape are all affected by the combined gravitational lensing effect of all that mass between them and us. In particular, we want to make accurate measurements of distances (cosmography), high redshift luminosity functions, and cluster masses, all of which count line of sight structure as one of their most serious systematic errors. More generally, we are interested in making maps for their own sake: the connection between galaxies and their dark matter halos is of fundamental importance for understanding galaxy formation and evolution.

Pangloss is scientific code, still under development, for holistically modeling mass in the Universe on galaxy and cluster scales. This wiki tries to show what we are doing with it; if you want to play around with the code yourself, please contact Phil Marshall to let us know you are here, and then see the README for more advice.

Code description

The code is documented in-place, but hopefully this page will help you navigate it.
