Over recent decades, cosmological simulations of galaxy formation have been instrumental
in advancing our understanding of structure and galaxy formation in the Universe. These …

A review is given of a priori predictions made for the dynamics of rotating galaxies. One
theory—MOND—has had many predictions corroborated by subsequent observations …

The strong equivalence principle (SEP) distinguishes general relativity (GR) from other
viable theories of gravity. The SEP demands that the internal dynamics of a self-gravitating …

Galaxies follow a tight radial acceleration relation (RAR): the acceleration observed at every
radius correlates with that expected from the distribution of baryons. We use the Markov …

Galactic rotation curves exhibit diverse behavior in the inner regions while obeying an
organizing principle; ie, they can be approximately described by a radial acceleration …

We present measurements of the radial gravitational acceleration around isolated galaxies,
comparing the expected gravitational acceleration given the baryonic matter (g bar) with the …

We examine the formation of dark matter (DM) cores in dwarf galaxies simulated with the
eagle model of galaxy formation. As in earlier work, we find that the star formation (SF) gas …

The mass profiles of massive dark matter halos are highly sensitive to the nature of dark
matter and potential modifications of the theory of gravity on large scales. The Λ cold dark …

We use a compilation of disc galaxy rotation curves to assess the role of the luminous
component ('baryons') in the rotation curve diversity problem. As in earlier work, we find that …

The missing gravity in galaxies requires dark matter, or alternatively a modification of gravity
or inertia. These theoretical possibilities of fundamental importance may be distinguished by …
