Vertical dynamics of disk galaxies in modified Newtonian dynamics [PDF]
Monthly Notices of the Royal Astronomical Society, 2007 We investigate the possibility of discriminating between modified Newtonian dynamics (MOND) and Newtonian gravity with dark matter, by studying the vertical dynamics of disc galaxies.

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 astrometrie and spectroscopic surveys.

Inkjet printing of non-Newtonian fluids [PDF]
, 2011 Jet breakup is strongly affected by fluid rheology. In particular,small amounts of polymer can cause substantially different breakup dynamics compared to a Newtonian jet, influencing in-flight fragmentation and detachment from the nozzle.

The shear-driven Rayleigh problem for generalised Newtonian fluids [PDF]
, 2014 We consider a variant of the classical ‘Rayleigh problem’ (‘Stokes’s first problem’) in which a semi-infinite region of initially quiescent fluid is mobilised by a shear stress applied suddenly to its boundary. We show that self-similar solutions for the

Geometry of modified Newtonian dynamics [PDF]
Physical Review D, 2012 Modified Newtonian Dynamics is an empirical modification to Poisson's equation which has had success in accounting for the `gravitational field' $Φ$ in a variety of astrophysical systems. The field $Φ$ may be interpreted in terms of the weak field limit of a variety of spacetime geometries.

Modified inertia as nonconservative Newtonian dynamics [PDF]
Physical Review D, 2021 Modified Newtonian dynamics by Milgrom is a paradigm for explaining the rotation curves of spiral galaxies and various other large scale structures. This paradigm includes several different theories. Here we present Milgrom's modified inertia (MI) theory in terms of a simple and tractable non-conservative Newtonian dynamics, which is useful in ...

New Relativistic Theory for Modified Newtonian Dynamics [PDF]
Physical Review Letters, 2021 We propose a relativistic gravitational theory leading to modified Newtonian dynamics, a paradigm that explains the observed universal galactic acceleration scale and related phenomenology. We discuss phenomenological requirements leading to its construction and demonstrate its agreement with the observed cosmic microwave background and matter power ...

Gravitational lensing in modified Newtonian dynamics [PDF]
Monthly Notices of the Royal Astronomical Society, 2001 AbstractGravitational 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. Lensing observations are a more powerful tool than dynamical measurements because they allow measurements of ...

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 in the Milky Way [PDF]
Monthly Notices of the Royal Astronomical Society, 2005 Both microlensing surveys and radio-frequency observations of gas flow imply that the inner Milky Way is completely dominated by baryons, contrary to the predictions of standard cold dark matter (CDM) cosmology. We investigate the predictions of the Modified Newtonian Dynamics (MOND) formula for the Galaxy given the measured baryon distribution ...
