It is proposed that the flat nature of the rotation curves of galaxies may be a result of the energy cascading processes occuring in turbulent galactic atmospheres. Thus, in this model, there is no need of invoking dark matter to account for the flat rotation curves of galaxies....
Confrontation of MOND with the rotation curves of early-type disc galaxies We extend the MOND analysis to a sample of 17 high surface brightness, early-type disc galaxies with rotation curves derived from a combination of 21cm HI ... RH Sanders,E Noordermeer - 《Monthly Notices of the Royal...

9. FIGURE CAPTIONS 1) Rotation curves of spiral galaxies under the generalized Einstein action. The numbers on the curves indicate the values of a in Eq. (2.23). The prediction of Newtonian theory for a = 2 is also given by a broken curve for comparison. 2) Scale factor of universe as...
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 properties, and c) Tully-Fisher rela...
galaxies: 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 from ...
rotation curves of these galaxies are more or less flat out to one or two Holmberg radii has been one of the key pieces of evi- dence for the existence of dark matter outside the optical disk (see also van Albada et al. 1985). Within the optical disk, the observed rotation curves ...

The rotation curves of three galaxies near M81 are determined on the basis of spectrograms obtained at 550-750 nm and dispersion 5 nm/mm at the prime focus of the 6-m telescope of the Special Astrophysical Observatory of the USSR Academy of Sciences during 1982. The data and results are ...
The 44 rotation curves of Sb and Sc galaxies are expressed by means of a linear least squares fit, from which the period of velolution and the ratio of tidal force to self-gravitating force are estimated for every galaxy in extreme cases. Finally, the measurement on two dimensional rotation...
