Dynamical friction in modified Newtonian dynamics [PDF]

Monthly Notices of the Royal Astronomical Society, 2008
We have tested a previous analytical estimate of the dynamical friction timescale in Modified Newtonian Dynamics (MOND) with fully non-linear N-body simulations.

Modified Newtonian dynamics (MOND)

This chapter presents Modified Newtonian Dynamics (MOND), the proposal that, below a certain acceleration scale $a_0$, dynamics departs from the Newtonian expectation.

Escaping from modified Newtonian dynamics [PDF]

Monthly Notices of the Royal Astronomical Society: Letters, 2007
We present a new test of modified Newtonian dynamics (MOND) on galactic scales, based on the escape speed in the solar neighbourhood. This test is independent from other empirical successes of MOND at reproducing the phenomenology of galactic rotation ...

Modified Newtonian Dynamics as an Entropic Force

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 if no dark matter component is introduced in the description of gravitational phenomena. The result

Cosmology with modified Newtonian dynamics (MOND) [PDF]

Monthly Notices of the Royal Astronomical Society, 1998
It is well-known that the application of Newtonian dynamics to an expanding spherical region leads to the correct relativistic expression (the Friedmann equation) for the evolution of the cosmic scale factor. Here, the cosmological implications of Milgrom's modified Newtonian dynamics (MOND) are considered by means of a similar procedure.

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 ...

On the gravitational potential of modified Newtonian dynamics [PDF]

Journal of Mathematical Physics, 2013
The mathematical structure of the Poisson equation of Modified Newtonian Dynamics (MOND) is studied. The appropriate setting turns out to be an Orlicz-Sobolev space whose Orlicz function is related to Milgrom's μ-function, where there exists existence and uniqueness of weak solutions.

Galaxy merging in modified Newtonian dynamics [PDF]

Monthly Notices of the Royal Astronomical Society: Letters, 2007
Abstract We present the results of N-body simulations of dissipationless galaxy merging in modified Newtonian dynamics (MOND). For comparison, we also studied Newtonian merging between galaxies embedded in dark matter haloes, with internal dynamics equivalent to the MOND systems.
