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. Satisfactory fits to the observationally determined terminal-velocity curve are obtained for different choices of MOND’s interpolating function µ(x… Expand

Milky Way potentials in cold dark matter and MOdified Newtonian Dynamics. Is the Large Magellanic Cloud on a bound orbit
We compute the Milky Way potential in different cold dark matter (CDM) based models, and compare these with the MOdified Newtonian Dynamics (MOND) framework. We calculate the axial ratio of theExpand
The Modified Newtonian Dynamics Fundamental Plane
Modified Newtonian dynamics (MOND) has been shown to be able to fit spiral galaxy rotation curves as well as giving a theoretical foundation for empirically determined scaling relations, such as theExpand
Galactic orbital motions in the dark matter, modified Newtonian dynamics and modified gravity scenarios
We simultaneously integrate in a numerical way the equations of motion of both the Magellanic Clouds (MCs) in the MOdified Newtonian Dynamics (MOND), MOdified Gravity (MOG) and cold dark matter (CDM)Expand
The thickness of H i in galactic discs under MOdified Newtonian Dynamics: theory and application to the Galaxy
The outskirts of galaxies are a very good laboratory for testing the nature of the gravitational field at low accelerations. By assuming that the neutral hydrogen gas is in hydrostatic equilibrium inExpand
Galactic Sun's motion in the cold dark matter, MOdified Newtonian Dynamics and modified gravity scenarios
We numerically integrate the equations of motion of the Sun in Galactocentric Cartesian rectangular coordinates for –4.5 Gyr ≤ t ≤ 0 in Newtonian mechanics with two different models for the Cold DarkExpand
Milky Way Mass Models and MOND
Using the Tuorla-Heidelberg model for the mass distribution of the Milky Way, I determine the rotation curve predicted by MOND (modified Newtonian dynamics). The result is in good agreement with theExpand
The distribution of mass in the orion dwarf galaxy
Dwarf galaxies are good candidates to investigate the nature of dark matter (DM), because their kinematics are dominated by this component down to small galactocentric radii. We present here theExpand
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
The escape velocity curve of the Milky Way in Modified Newtonian Dynamics
We determine the escape velocity from the Milky Way (MW) at a range of Galactocentric radii in the context of Modified Newtonian Dynamics (MOND). Due to its non-linear nature, escape is possible ifExpand
N-body simulations of the carina dSph in MOND
The classical dwarf spheroidals (dSphs) provide a critical test for Modified Newtonian Dynamics (MOND) because they are observable satellite galactic systems with low internal accelerations and low,Expand


ΛCDM-based Models for the Milky Way and M31. I. Dynamical Models
We apply standard disk formation theory with adiabatic contraction within cuspy halo models predicted by the standard cold dark matter (?CDM) cosmology. The resulting models are confronted with theExpand
The present and future mass of the Milky Way halo
A simple model for the Milky Way halo is presented. It has a flat rotation curve in the inner regions, but the density falls off sharply beyond an outer edge. This truncated, flat rotation curve (TF)Expand
Gas dynamics in the Milky Way: second pattern speed and large-scale morphology
We present new gas flow models for the Milky Way inside the solar circle. We use smoothed particles hydrodynamics (SPH) simulations in gravitational potentials determined from the near-infrared (NIR)Expand
We build a stellar-dynamical model of the Milky Way's barred bulge and disk, using a newly implemented adaptive particle method. The underlying mass model has been previously shown to match theExpand
Using distant globular clusters as a test for gravitational theories
We propose to determine the stellar velocity dispersions of globular clusters in the outer halo of the Milky Way in order to decide whether the dynamics of the Universe on large scales is governed byExpand
Refining the Oort and Galactic constants
The local stellar kinematics of the Milky Way offer a useful tool for studying the rotation curve of the Galaxy. These kinematics — usually parametrized by the Oort constants AB— depend on the localExpand
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
The photometric structure of the inner Galaxy
The light distribution in the inner few kiloparsecs of the Milky Way is recovered non­ parametrically from a dust-corrected near-infrared COBEIDIRBE surface brightness map of the inner Galaxy. TheExpand
Dynamics with a Nonstandard Inertia-Acceleration Relation: An Alternative to Dark Matter in Galactic Systems
Abstract We investigate particle dynamics that is governed by a nonstandard kinetic action of a special form. We are guided by a phenomenological scheme-the modified dynamics (MOND)-that imputes 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
