From Modified Newtonian Dynamics to Superfluid Vacuum Theory [PDF]
Entropy, 2022 Herein is a review of the essentials of Modified Newtonian Dynamics (MOND) versus dark matter models based on Superfluids for modeling galactic rotation curves. We review the successes and issues of both approaches.

Phase Transition in Modified Newtonian Dynamics (MONDian) Self-Gravitating Systems [PDF]
Entropy, 2021 We study the statistical mechanics of binary systems under the gravitational interaction of the Modified Newtonian Dynamics (MOND) in three-dimensional space.

Khronometric Theories of Modified Newtonian Dynamics
The Astrophysical Journal, 2023 In 2011 Blanchet and Marsat suggested a fully relativistic version of Milgrom's modified Newtonian dynamics in which the dynamical degrees of freedom consist of the spacetime metric and a foliation of spacetime, the khronon field.

Dissipationless Collapses in Modified Newtonian Dynamics [PDF]
The Astrophysical Journal, 2007 Dissipationless collapses in modified Newtonian dynamics (MOND) are studied by using a new particle-mesh N-body code based on our numerical MOND potential solver. We found that low surface density end products have shallower inner density profiles, flatter radial velocity dispersion profiles, and more radially anisotropic orbital distributions than ...

Modified Newtonian dynamics of large-scale structure [PDF]
Monthly Notices of the Royal Astronomical Society, 2002 We examine the implications of Modified Newtonian Dynamics (MOND) on the large scale structure in a Friedmann-Robertson-Walker universe. We employ a ``Jeans swindle'' to write a MOND-type relationship between the fluctuations in the density and the gravitational force, $\vg$.

Modified Newtonian Dynamics (MOND) as a Modification of Newtonian Inertia [PDF]
Journal of Astrophysics and Astronomy, 2017 We present a modified inertia formulation of Modified Newtonian dynamics (MOND) without retaining Galilean invariance. Assuming that the existence of a universal upper bound, predicted by MOND, to the acceleration produced by a dark halo is equivalent to a violation of the hypothesis of locality (which states that an accelerated observer is pointwise ...

Modified Newtonian Dynamics (MOND): Observational Phenomenology and Relativistic Extensions [PDF]
Living Reviews in Relativity, 2012 A wealth of astronomical data indicate the presence of mass discrepancies in the Universe. The motions observed in a variety of classes of extragalactic systems exceed what can be explained by the mass visible in stars and gas. Either (i) there is a vast

The Magellanic Stream in Modified Newtonian Dynamics [PDF]
The Astrophysical Journal, 2006 The dynamics of the Magellanic Stream (MS) as a series of clouds extending from the Magellanic Clouds (MCs) to the south Galactic pole is affected by the distribution and the amount of matter in the Milky Way. We calculate the gravitational effect of the Galactic disk on the MS in the framework of modified Newtonian dynamics(MOND) and compare with ...

Oscillating Cosmological Force Modifies Newtonian Dynamics [PDF]
Galaxies, 2020 In the Newtonian limit of general relativity a force acting on a test mass in a central gravitational field is conventionally defined by the attractive Newtonian gravity (inverse square) term plus a small repulsive cosmological force, which is ...
