Within the cold dark matter (CDM) framework tidal dwarf galaxies (TDGs) cannot contain dark matter, so the recent results by Bournaud et al. (2007, Science, 316, 1166) that 3 rotating TDGs do show significant evidence for being dark matter dominated is inconsistent with the current concordance cosmological theory unless yet another dark matter component is postulated. We confirm that the TDG rotation curves are consistent with Newtonian dynamics only if either an additional dark matter… Expand

Young tidal dwarf galaxies cannot be used to probe dark matter in galaxies
The location of dark-matter free, tidal dwarf galaxies (TDGs) in the baryonic Tully Fisher (bTF) diagram has been used to test cosmological scenarios, leading to various and controversial results.Expand
Tidal Dwarf Galaxies : Disc Formation at z=0
Collisional debris around interacting and post-interacting galaxies often display condensations of gas and young stars that can potentially form gravitationally bound objects: Tidal Dwarf GalaxiesExpand
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
Lessons from the Local Group (and beyond) on dark matter
The existence of exotic dark matter particles outside the standard model of particle physics constitutes a central hypothesis of the current standard model of cosmology (SMoC). Using a wide range ofExpand
Galaxies as simple dynamical systems: observational data disfavor dark matter and stochastic star formation
According to modern theory, galactic evolution is driven by the dynamics of dark matter and stochastic star formation, but galaxies are observed to be simple systems. The existence of dark matterExpand
The recent years have seen combined measurements of X-ray and (weak) lensing contours for colliding galaxy clusters such as, for instance, the famous 'Bullet' cluster. These observations haveExpand
MONDian dark matter (MDM) is a new form of dark matter quantum that naturally accounts for Milgrom's scaling, usually associated with modified Newtonian dynamics (MOND), and theoretically behavesExpand
The survival of dynamical fossils in dwarf spheroidal galaxies in conventional and modified dynamics
The survival of unbound density substructure against orbital mixing imposes strong constraints on the slope of the underlying gravitational potential and provides a new test on modified gravities.Expand
MOND plus classical neutrinos are not enough for cluster lensing
Clusters of galaxies offer a robust test bed for probing the nature of dark matter that is insensitive to the assumption of the gravity theories. Both Modified Newtonian Dynamics (MOND) and GeneralExpand
Gas dynamics in tidal dwarf galaxies: disc formation at z = 0 ?
Tidal dwarf galaxies (TDGs) are recycled objects that form within the collisional debris of interacting/merging galaxies. They are expected to be devoid of non-baryonic dark matter, since they canExpand


MOND and the mass discrepancies in tidal dwarf galaxies
I consider in light of MOND the three debris galaxies discussed recently by Bournaud et al.. These exhibit mass discrepancies of a factor of a few within several scale lengths of the visible galaxy,Expand
Modified Newtonian dynamics in the Milky Way
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 matterExpand
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
From tidal dwarf galaxies to satellite galaxies
Received; accepted Abstract. The current popular cosmological models have granted to the population of dwarf satellite galaxies a key role: their number, location and masses constrain both theExpand
NGC 3741: the dark halo profile from the most extended rotation curve
We present new H i observations of the nearby dwarf galaxy NGC 3741. This galaxy has an extremely extended H i disc, which allows us to trace the rotation curve out to unprecedented distances inExpand
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
Formation of dwarf galaxies in tidal tails
ZWICKY1 argued long ago that tidal forces can tear long tails of stars and gas from the bodies of interacting disk galaxies, and that this debris may include self-gravitating objects which couldExpand
Roche lobe shapes for testing MOND-like modified gravities
Dark Matter (DM) theories and mass-tracing-light theories like MOND are by construction nearly degenerate on galactic scales, but not when it comes to the predicted shapes of Roche Lobes of aExpand
Search for tidal dwarf galaxy candidates in a sample of ultraluminous infrared galaxies
Context. Small star-forming galaxies made out of collisional debris have been found in a variety of merging systems. So far only a few of them are known in Ultraluminous Infrared Galaxies (ULIRGs)Expand
