We compare the MOG and MOND predictions of the Tully-Fisher relationship to observations using gas-rich galaxies for which the baryonic mass can be estimated accurately. We find that both theories are in good agreement with the data. Future observations of large, gas-rich galaxies may offer a means to distinguish between these two theories.

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
THE BARYONIC TULLY–FISHER RELATION OF GAS-RICH GALAXIES AS A TEST OF ΛCDM AND MOND
The baryonic Tully–Fisher relation (BTFR) is an empirical relation between baryonic mass and rotation velocity in disk galaxies. It provides tests of galaxy formation models in ΛCDM and of
