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.

Modified Newtonian Dynamics of Large Scale Structure [PDF]

Monthly Notices of the Royal Astronomical Society, 2001
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 ...

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 ...

A historical perspective on Modified Newtonian Dynamics [PDF]

Canadian Journal of Physics, 2014
I review the history and development of Modified Newtonian Dynamics (MOND) beginning with the phenomenological basis as it existed in the early 1980s. I consider Milgrom's papers of 1983 introducing the idea and its consequences for galaxies and galaxy ...

Debye entropic force and modified Newtonian dynamics [PDF]

Communications in Theoretical Physics, 2010
Verlinde has suggested that the gravity has an entropic origin, and a gravitational system could be regarded as a thermodynamical system. It is well-known that the equipartition law of energy is invalid at very low temperature.

Modified Newtonian Dynamics as an entropic force [PDF]

Journal of Modern Physics, 2015
Under natural assumptions on the thermodynamic properties of space and time with the holographic principle we reproduce a MOND-like behaviour of gravity on particular scales of mass and length, where Newtonian gravity requires a modification or extension

Theoretically Motivated Dark Electromagnetism as the Origin of Relativistic Modified Newtonian Dynamics [PDF]

Universe
The present paper is a modest attempt to initiate the research program outlined in this abstract. We propose that general relativity and relativistic MOND (RelMOND) are analogues of broken electroweak symmetry.

Galactic kinematics with modified Newtonian dynamics [PDF]

Astronomy & Astrophysics, 2009
We look for observational signatures that could discriminate between Newtonian and modified Newtonian (MOND) dynamics in the Milky Way, in view of the advent of large astrometric and spectroscopic surveys.

Large-scale filaments--Newtonian vs. modified dynamics [PDF]

The Astrophysical Journal, 1996
Eisenstein Loeb and Turner (ELT) have recently proposed a method for estimating the dynamical masses of large-scale filaments, whereby the filament is modeled by an axisymmetric, isothermal cylinder, for which ELT derive a global relation between the ...

Testing modified Newtonian dynamics in the Milky Way [PDF]

Physical Review D, 2015
Modified Newtonian dynamics (MOND) is an empirical theory originally proposed to explain the rotation curves of spiral galaxies by modifying the gravitational acceleration, rather than by invoking dark matter.
