Classical MW satellites have high MOND tidal susceptibility at pericentre that matches their observed tidal features and elevated dispersions, while CDM predicts they should be largely resilient.

abstract
Recycled dwarf galaxies can form in the collisional debris of massive galaxies. Theoretical models predict that, contrary to classical galaxies, they should be free of non-baryonic Dark Matter. Analyzing the observed gas kinematics of such recycled galaxies with the help of a numerical model, we demonstrate that they do contain a massive dark component amounting to about twice the visible matter. Staying within the standard cosmological framework, this result most likely indicates the presence of large amounts of unseen, presumably cold, molecular gas. This additional mass should be present in the disks of their progenitor spiral galaxies, accounting for a significant part of the so-called missing baryons.

The tidal features of the classical Milky Way satellites: Expected in MOND but inconsistent with cold dark matter models
Classical MW satellites have high MOND tidal susceptibility at pericentre that matches their observed tidal features and elevated dispersions, while CDM predicts they should be largely resilient.
