Gravitational lensing in modified Newtonian dynamics [PDF]
Modified Newtonian dynamics (MOND) is an alternative theory of gravity that aims to explain large-scale dynamics without recourse to any form of dark matter.

From Modified Newtonian Dynamics to Superfluid Vacuum Theory [PDF]
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.

Modified Newtonian Dynamics (MOND): Observational Phenomenology and Relativistic Extensions [PDF]
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 Geometry Of Modified Newtonian Dynamics [PDF]
Modified Newtonian Dynamics is an empirical modification to Poisson's equation which has had success in accounting for the `gravitational field' $\Phi$ in a variety of astrophysical systems.

Vertical dynamics of disk galaxies in MOND [PDF]
We investigate the possibility of discriminating between Modified Newtonian Dynamics (MOND) and Newtonian gravity with dark matter, by studying the vertical dynamics of disk galaxies.

Modified Newtonian dynamics and non-relativistic ChSAS gravity
In the context of the non-relativistic theories, a generalization of the Chern–Weil-theorem allows us to show that extended Chern–Simons actions for gravity in d=4 invariant under some specific non-relativistic groups lead to modified Poisson equations ...

Modified Newtonian Dynamics as an Alternative to the Planet Nine Hypothesis [PDF]
A new class of Kuiper Belt objects (KBOs) that lie beyond Neptune with semimajor axes greater than 250 astronomical units show orbital anomalies that have been interpreted as evidence for an undiscovered ninth planet.

Radial-orbit instability in modified Newtonian dynamics [PDF]
The stability of radially anisotropic spherical stellar systems in modified Newtonian dynamics (MOND) is explored by means of numerical simulations performed with the N-body code N-MODY.

Dynamics of Elliptical Galaxies with Planetary Nebulae in Modified Newtonian Dynamics [PDF]
The dynamics of an elliptical galaxy within a couple of effective radii can be probed effectively by stars. However, at larger distances planetary nebulae (PNe) replace stars as the tracer of the dynamics.
