It's worth taking a look. Hard to believe that under "the weak gravitational fields under consideration" (quote from the abstract) that general relativity would make that much of a difference, though. If their (Cooperstock and Tieu, University of Victoria, with some recognition from the Gravity Research Foundation) calculations are correct, maybe the original ones (that showed a dark matter halo) are wrong.
