Not a MOND proponent but why does it exactly contradict it? It’s a UDG with very little to no star forming gas and very low overall mass and density, looking up the galaxy it’s about the same size Milky Way but has less than 0.5% of its stars and much less than that when it comes to overall mass. It seems that there are some papers that attempt to reconcile the observations with MOND and on the face of it the velocities expected if MOND holds true and are not far off from the current observations. https://arxiv.org/abs/1804.04167 Considering the distance of the galaxy (72m light years) and…
