Globular clusters (GCs) in the Milky Way have characteristic velocity dispersions that are consistent with the predictions of Newtonian gravity, and may be at odds with Modified Newtonian Dynamics (MOND). We discuss a modified gravity (MOG) theory that successfully predicts galaxy rotation curves, galaxy cluster masses and velocity dispersions, lensing, and cosmological observations, yet produces predictions consistent with Newtonian theory for smaller systems, such as GCs. MOG produces… 

Globular clusters in modified Newtonian dynamics: velocity-dispersion profiles from self-consistent models

We test the modified Newtonian dynamics (MOND) theory with the velocity dispersion profiles of Galactic globular clusters populating the outermost region of the Milky Way halo, where the Galactic

Eventual flattening of velocity dispersion profiles of some galactic globular clusters (GCs) in the Milky Way cannot be explained in the framework of Newtonian gravity and hence in general theory

Testing Newtonian gravity with distant globular clusters: NGC 1851 and NGC 1904

Context. Globular clusters are useful for testing the validity of Newtonian dynamics in the low acceleration regime typical of galaxies, without the complications of non-baryonic dark matter. In the

Application of three-body stability to globular clusters - II. Observed velocity dispersions

The velocity dispersion profile in globular clusters (GCs) is explained here without having to rely on dark matter or a modification of Newtonian dynamics (MOND). The flattening of the velocity

Testing Newtonian gravity with AAOmega: mass-to-light profiles of four globular clusters

Testing Newtonian gravity in the weak-acceleration regime is vital to our understanding of the nature of the gravitational interaction. It has recently been claimed that the velocity dispersion

Flattened velocity dispersion profiles in Globular Clusters: Newtonian tides or modified gravity?

Over the past couple of years, a number of observational studies have confirmed the flattening of the radial velocity dispersion profiles for stars in various nearby globular clusters. As the


In the context of theories of gravity modified to account for the observed dynamics of galactic systems without the need to invoke the existence of dark matter, a prediction often appears regarding

Testing Weyl gravity at galactic and extra-galactic scales

We examine the viability of Weyl conformal gravity as an alternative to the general theory of relativity. By using the extended rotation curve of the Milky Way and velocity dispersions of four

Testing Newtonian gravity in the low acceleration regime with globular clusters: the case of ω Centauri revisited

Context. Stellar kinematics in the external regions of globular clusters can be used to probe the validity of Newton’s law in the low acceleration regimes without the complication of non-baryonic

Testing Modified Gravity with Dwarf Spheroidal Galaxies

The observed velocity dispersion of the classical dwarf spheroidal (dSph) galaxies of the Milky Way (MW) requires the Newtonian stellar mass-to-light ($M_*/L$) ratios in the range of about 10 to more



Using distant globular clusters as a test for gravitational theories

We propose to determine the stellar velocity dispersions of globular clusters in the outer halo of the Milky Way in order to decide whether the dynamics of the Universe on large scales is governed by

Modified Gravitational Theory and Galaxy Rotation Curves

The nonsymmetric gravitational theory predicts an acceleration law that modifies the Newtonian law of attraction between particles. For weak fields a fit to the flat rotation curves of galaxies is

Using globular clusters to test gravity in the weak acceleration regime

We have carried out a study of the velocity dispersion of the stars in the outskirts of the globular cluster ω Cen, finding that the velocity dispersion remains constant at large radii rather than

Testing modified gravity with motion of satellites around galaxies

A modified gravity (MOG) theory, that has been successfully fitted to galaxy rotational velocity data, cluster data, the Bullet Cluster 1E0657-56 and cosmological observations, is shown to be in good


The motion of satellite galaxies around normal galaxies at distances 50–500 kpc provides a sensitive test for theories. We study the surface density and velocities of satellites around isolated red

Gravitational theory, galaxy rotation curves and cosmology without dark matter

Einstein gravity coupled to a massive skew symmetric field Fμνλ leads to an acceleration law that modifies the Newtonian law of attraction between particles. We use a framework of non-perturbative

Galaxy Rotation Curves without Nonbaryonic Dark Matter

We apply the modified acceleration law obtained from Einstein gravity coupled to a massive skew-symmetric field Fμνλ to the problem of explaining galaxy rotation curves without exotic dark matter.

Galaxy cluster masses without non-baryonic dark matter

We apply the modified acceleration law obtained from Einstein gravity coupled to a massive skew symmetric field, Fμνλ, to the problem of explaining X-ray galaxy cluster masses without exotic dark

Modified Newtonian dynamics in the Milky Way

Both microlensing surveys and radio-frequency observations of gas flow imply that the inner Milky Way is completely dominated by baryons, contrary to the predictions of standard cold dark matter

Fundamental parameter-free solutions in modified gravity

Modified gravity (MOG) has been used successfully to explain the rotation curves of galaxies, the motion of galaxy clusters, the bullet cluster and cosmological observations without the use of dark
