The mass discrepancy in disk galaxies is shown to be well correlated with acceleration, increasing systematically with decreasing acceleration below a critical scale a0 � 3700 km 2 s � 2 kpc � 1 ¼ 1:2 ; 10 � 10 ms � 2 .F or each galaxy, there is an optimal choice of stellar mass-to-light ratio that minimizes the scatter in this mass discrepancy–acceleration relation. The same mass-to-light ratios also minimize the scatter in the baryonic TullyFisher relation and are in excellent agreement with… Expand
The mass discrepancy acceleration relation in early-type galaxies: extended mass profiles and the phantom menace to MOND
The dark matter (DM) haloes around spiral galaxies appear to conspire with their baryonic content: empirically, significant amounts of DM are inferred only below a universal characteristicExpand
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
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 distribution of mass components in simulated disc galaxies
Using 22 hydrodynamical simulated galaxies in a LCDM cosmological context we recover not only the observed baryonic Tully-Fisher relation, but also the observed "mass discrepancy--acceleration"Expand
The radial acceleration relation and dark baryons in MOND
Recent observations of rotationally supported galaxies show a tight correlation between the observed radial acceleration at every radius and the Newtonian acceleration generated by the baryonic massExpand
Mass discrepancy–acceleration relation in Einstein rings
We study the Mass Discrepancy-Acceleration Relation (MDAR) of 57 elliptical galaxies by their Einstein rings from the Sloan Lens ACS Survey (SLACS). The mass discrepancy between the lensing mass andExpand
Galaxy phenomenology from dark matter-baryon interactions
There is strong evidence that the mass discrepancy in spiral galaxies anticorrelates with the baryonic acceleration, i.e. it follows a mass discrepancy-acceleration relation “MDAR”. The observedExpand
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
Emergence of the mass discrepancy-acceleration relation from dark matter-baryon interactions
The observed tightness of the mass discrepancy-acceleration relation (MDAR) poses a fine-tuning challenge to current models of galaxy formation. We propose that this relation could arise fromExpand
The mass discrepancy acceleration relation in a ΛCDM context
The mass discrepancy acceleration relation (MDAR) describes the coupling between baryons and dark matter (DM) in galaxies: the ratio of total-to-baryonic mass at a given radius anti-correlates withExpand

Mass models of spiral galaxies based on the observed light distribution, assuming constant M /L for bulge and disc, are able to reproduce the observed rotation curves in the inner regions, but failExpand
Simulating observations of dark matter dominated galaxies: towards the optimal halo profile
Low surface brightness galaxies are dominated by dark matter, and their rotation curves thus reflect their dark matter distribution. Recent high-resolution rotation curves suggest that their darkExpand
Modified dynamics (MOND) as a dark halo
We propose a form for dark haloes that embodies the fundamental aspect of Milgrom's modified dynamics (MOND): the discrepancy between the visible mass and the Newtonian dynamical mass appears below aExpand
The visible matter - dark matter coupling
In the inner parts of spiral galaxies, of high or low surface brightness, there is a close correlation between rotation curve shape and light distribution. For any feature in the luminosity profileExpand

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

A low mass-to-light (M/L) ratio for the stellar component of spiral galaxies (M/L≲ 1 in the I band) is advocated by various dynamical arguments and by recent cosmological simulations of the formationExpand
