Newtonian Fractional-Dimension Gravity and Galaxies without Dark Matter
Universe, 2023 We apply Newtonian fractional-dimension gravity (NFDG), an alternative gravitational model, to some notable cases of galaxies with little or no dark matter.

JPSE (Journal of Physical Science and Engineering), 2022 The rotation curve of galaxies for M33 in 1959 by Louise Volders gave the new hypothetical about the invisible matter that contributes inside of the galaxy, which later we call dark matter (DM).

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 ...

Gravitational lensing and modified Newtonian dynamics [PDF]
, 2001 Gravitational lensing is most often used as a tool to investigate the distribution of (dark) matter in the universe, but, if the mass distribution is known a priori, it becomes, at least in principle, a powerful probe of gravity itself.

The Local Group as a test system for Modified Newtonian Dynamics [PDF]
Physics of the Dark Universe, 2020 The Local Group (LG) is {an appropriate} test system for Modified Newtonian Dynamics, since the acceleration of M31 galaxy is fully in the deep MOND regime $a \ll a_0$.

Relativistic Khronon theory in agreement with modified Newtonian dynamics and large-scale cosmology [PDF]
Journal of Cosmology and Astroparticle PhysicsWe propose an extension of General Relativity (GR) based on a space-time foliation by three-dimensional space-like hypersurfaces labeled by the Khronon scalar field τ.

Newtonian and modified newtonian gravitational simulation of spiral galaxies
Iraqi Journal of Physics, 2019 One of the most powerful tools for any stellar dynamics is the N-body simulation. In an N-body simulation the motion of N particles is followed under their mutual gravitational attraction.
