Milky Way potentials in CDM and MOND. Is the Large Magellanic Cloud on a bound orbit?
Xufen Wu, Benoit Famaey, Gianfranco Gentile +2
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 axis…
Neutrinos as galactic dark matter in the Ursa Major galaxy group?
G. Gentile, H. S. Zhao, B. Famaey
We present the analysis of 23 published rotation curves of disk galaxies belonging to the Ursa Major group of galaxies, with kinematics free of irregularities. The rotation curves…
Velocity dispersion around ellipticals in MOND
O. Tiret, F. Combes, G. W. Angus +2
We investigate how different models that have been proposed for solving the dark matter problem can fit the velocity dispersion observed around elliptical galaxies, on either a sma…
Tidal dwarf galaxies as a test of fundamental physics
G. Gentile, B. Famaey, F. Combes +3
Within the cold dark matter (CDM) framework tidal dwarf galaxies (TDGs) cannot contain dark matter, so the recent results by Bournaud et al. (2007) that 3 rotating TDGs do show sig…
Loss of mass and stability of galaxies in MOND
Xufen Wu, HongSheng Zhao, Benoit Famaey +5
The self-binding energy and stability of a galaxy in MOND-based gravity are curiously decreasing functions of its center of mass acceleration towards neighbouring mass concentratio…
Escaping from MOND
Benoit Famaey, Jean-Philippe Bruneton, HongSheng Zhao
We present a new test of modified Newtonian dynamics (MOND) on galactic scales, based on the escape speed in the solar neighbourhood. This test is independent from other empirical…
