Dynamical Friction and the Distribution of Dark Matter in Barred Galaxies
Open accessAbstract
We use fully self-consistent N -body simulations of barred galaxies to show that dynamical friction from a dense dark matter halo dramatically slows the rotation rate of bars. Our result supports previous theoretical predictions for a bar rotating within a massive halo. On the other hand, low-density halos, such as those required for maximum disks, allow the bar to continue to rotate at a high rate. There is somewhat meager observational evidence indicating that bars in real galaxies do rotate rapidly, and we use our result to argue that dark matter halos must have a low central density in all high surface brightness disk galaxies, including the Milky Way. Bars in galaxies that have larger fractions of dark matter should rotate slowly, and we suggest that a promising place to look for such candidate objects is among galaxies of intermediate surface brightness.

“The M/L values of the luminous matter are uncertain and the fitted functional form for the halo is generally chosen arbitrarily (e.g., Broeils 1992, but see also Navarro et al. 1996).”

“There is also some disagreement over the precise size (Weinberg 1992; Dwek et al. 1995) and pattern speed of the bar (Binney et al. 1991; Kalnajs 1996), but it seems unlikely that the value ofDL/aB will turn out to be substantially larger than for other barred galaxies.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
