The current cosmological paradigm, the cold dark matter model with a cosmological constant, requires that the mass-energy of the Universe be dominated by invisible components: dark matter and dark energy. An alternative to these dark components is that the law of gravity be modified on the relevant scales. A test of these ideas is provided by the baryonic Tully-Fisher relation (BTFR), an empirical relation between the observed mass of a galaxy and its rotation velocity. Here, I report a test… Expand
Modified Newtonian Dynamics (MOND): Observational Phenomenology and Relativistic Extensions
It is shown that many of these puzzling observations are predicted by one single relation — Milgrom’s law — involving an acceleration constant a0 on the order of the square-root of the cosmological constant in natural units. Expand
Anomalous Galactic Dynamics by Collusion of Rindler and Cosmological Horizons
In holography, the dimensional reduction of phase space to two dimensions defines a dynamical dark energy of , associated with the cosmological horizon at a Hubble radius of , and inertia m ofExpand
Dark Matters on the Scale of Galaxies
The cold dark matter model successfully explains both the emergence and evolution of cosmic structures on large scales and, when we include a cosmological constant, the properties of the homogeneousExpand
The baryonic Tully-Fisher relation (BTFR) is an empirical relation between baryonic mass and rotation velocity in disk galaxies. It provides tests of galaxy formation models in ΛCDM and ofExpand
Gravitational potentials in the cosmos are deeper than expected from observed visible objects, a phenomenon usually attributed to dark matter, presumably in the form of a new fundamental particle.Expand
Testing two alternative theories to dark matter with the Milky Way dynamics
Two alternative theories to dark matter are investigated by testing their ability to describe consistently the dynamics of the Milky Way. The first one refers to a modified gravity theory having aExpand
Towards a new generalized space expansion dynamics applied to the rotation of galaxies and Tully Fisher law
Up to now, the rotational velocities of galaxies are not clearly understood and the experimental Tully Fisher rule, linking the total galactic mass to the fourth power of the velocity, through anExpand
Galactic rotation curves, the baryon-to-dark-halo-mass relation and space–time scale invariance
Low-acceleration space-time scale invariant dynamics (SID, Milgrom 2009a) predicts two fundamental correlations known from observational galactic dynamics: the baryonic Tully-Fisher relation (BTFR)Expand
The abundance of galaxy clusters in MOND: Cosmological simulations with massive neutrinos
We present a new Particle-Mesh cosmological N-body code for accurately solving the modified Poisson equation of the Quasi Linear formulation of MOND. We generate initial conditions for the AngusExpand
The Third Law of Galactic Rotation
I review the connection between dynamics and the baryonic mass distribution in rotationally supported galaxies. The enclosed dynamical mass-to-light ratio increases with decreasing galaxy luminosityExpand


Modified Newtonian Dynamics: A Falsification of Cold Dark Matter
The only viable alternative to dark matter is one in which Newtonian dynamics or gravity breaks down in the limit of low accelerations, as in modified Newtonian dynamics (MONDs). This hypothesis,Expand
Modified Newtonian dynamics as an alternative to dark matter
▪ Abstract Modified Newtonian dynamics (MOND) is an empirically motivated modification of Newtonian gravity or inertia suggested by Milgrom as an alternative to cosmic dark matter. The basic idea isExpand
Reconciling MOND and dark matter
Observations of galaxies suggest a one-to-one analytic relation between the inferred gravity of dark matter at any radius and the enclosed baryonic mass, a relation summarized by Milgrom's law ofExpand
Galaxy Rotation Curves without Nonbaryonic Dark Matter
We apply the modified acceleration law obtained from Einstein gravity coupled to a massive skew-symmetric field Fμνλ to the problem of explaining galaxy rotation curves without exotic dark matter.Expand
Gravitational polarization and the phenomenology of MOND
The modified Newtonian dynamics (MOND) has been proposed as an alternative to the dark matter paradigm; the philosophy behind is that there is no dark matter and we witness a violation of theExpand
Extended rotation curves of spiral galaxies: dark haloes and modified dynamics
Strict criteria are applied to the sample of spiral galaxies with measured rotation curves in order to select those objects for which the observed rotation curve is an accurate tracer of the radialExpand

Testing the dark matter hypothesis with low surface brightness galaxies and other evidence
The severity of the mass discrepancy in spiral galaxies is strongly correlated with the central surface brightness of their disks. Progressively lower surface brightness galaxies have ever largerExpand
The baryonic Tully-Fisher relation and its implication for dark matter halos
Context. The baryonic Tully-Fisher relation (BTF) is a fundamental relation between baryonic mass and maximum rotation velocity. It can be used to estimate distances, as well as to constrain theExpand
Large scale structure in Bekenstein's theory of relativistic modified Newtonian dynamics.
It is shown that it may be possible to reproduce observations of the cosmic microwave background and galaxy distributions with Bekenstein's theory of MOND, and the evolution of the scalar field is akin to that of tracker quintessence fields. Expand
