We apply the modified acceleration law obtained from Einstein gravity coupled to a massive skew symmetric field, Fμνλ, to the problem of explaining X-ray galaxy cluster masses without exotic dark matter. Utilizing X-ray observations to fit the gas mass profile and temperature profile of the hot intr...
