probabilistic halo mass inference

In a low-research day, at lunch, Kilian Walsh pitched to Fadely and me a project to infer galaxy host halo masses from galaxy positions and redshifts. We discussed some of the issues and previous work. I am out of the loop, so I don't know the current literature. But I am sure there is interesting work that can be done, and it would be fun to combine galaxy kinematic information with weak lensing, strong lensing, x-ray, and SZ effect data.
