Dark mattergalaxies: stars: rotation curvesThe dark matter accretion theory (around a central body) of the author on the basis of his 5-dimensional Projective Unified Field Theory (PUFT) is applied to the orbital motion of stars around the center of the Galaxy. The departure of the motion ...
rotation curves of galaxies 摘要 There is ample evidence from rotation curves that dark matter halos around disk galaxies have nontrivial dynamics. Of particular significance are: a) the cored dark matter profile of disk galaxies, b) correlations of the shape of rotation curves with baryonic prope...
The fundamental properties of the dark matter in this model are determined by two parameters only, the mass and the scattering length of the particle. In the present study we investigate the properties of the galactic rotation curves in the BEC dark matter model, with quadratic self-interaction,...
Semi-analytical method is used to derive rotation curves for such a clumpy dark matter density profile. It is found that the halo substructures significantly affect the galaxy velocity field. Based on the fractal geometry of the halo, this self-consistent model predicts an NFW-like rotation curve...

Rotation curves of dark matter-dominated galaxies measure the mass profiles of galactic halos and thereby test theories of their cosmological origin. While attention has focused lately on the possible discrepancy at small galactocentric radii between observed rotation curves and the singular density profil...
If dark matter halos do not exist (as shown above), gravity in galactic outskirts should be Newtonian. Instead, they exhibit flat rotation curves out to where gas can still be measured, which is typically two dozen kpc from the centre of a major disk galaxy like the MW. A way to descri...
Rotation curves place important constraints on the radial mass distribution of dark matter halos,ρ(r). At large radii, rotation curves tend to become asymptotically flat. Forρ(r) ∝ rα, this impliesα ≈ -2, which persists as far out as can be measured. At small radii, the data ...
We study the rotation curves of ultralight BEC dark matter halos. These halosare long lived solutions of initially rotating BEC fluctuations. In order tostudy the implications of the rotation characterizing these long-livedconfigurations we consider the particular case of a boson mass$m=10^{-23}\...
