Query: NGC 1052-DF2 And Modified Gravity (MOG) Without Dark Matter   We model the velocity dispersion of the ultra-diffuse galaxy NGC 1052-DF2
using Newtonian gravity and modified gravity (MOG). The velocity dispersion
predicted by MOG is higher than the Newtonian gravity prediction, but it is
fully consistent with the observed velocity dispersion that is obtained from
the motion of 10 globular clusters.
