named mirinae force, generated by the mass of relatively-moving particles, and demonstrate that this force explains the rotation curve and evolution of a galaxy in which some of the inner mass of the supermassive black hole at the galactic center is assumed to be revolving at a relativistic sp...
GalaxyRotation CurveThe purpose is to treat the rotation curve of our galaxy, almost flat. The main cause would be due to the dark matter, which still has not been found. Thus, it is here proposed a disk model in 1/r within Newtonian mechanics. In such case, it is calculated the ...
4.3.1Galaxy Rotation Curves Much of the evidence comes from the motions of galaxies. A galaxy rotation curve is a plot of theorbital velocities(i.e., the speeds) of visible stars or gas in that galaxy versus their radial distance from that galaxy's center. The rotational speed of galaxies...
this led to a remarkably small gravitational coupling G variation (about or less than 10^{-12} of its value per light-year), while also capable of generating galaxy rotation curves about as good as the best phenomenological dark matter profiles (considering both the rotation curve shape and th...
The rotation curve data for spiral galaxies are consistent with the dark matter distributed in their halo. This dark halo constitutes much of the galaxys total mass. All baryonic matter (stars, star clusters, ISM, etc.) are held together by the gravitational potential of this dark matter halo...
The rotation curve (RC) of our Galaxy, the Milky Way, is constructed starting from its very inner regions (few hundred pc) out to a large Galactocentric distance of \\sim 200 \\sim 200 kpc using kinematical data on a variety of tracer objects moving in the gravitational potential of the...
In this work, the results after four of these iterations, have provided a reasonable fit to the observed galaxy rotation curve, We solved Eq. (49), with \(s=\frac{1}{\phi }\), using 3D DCT with Octave (a clone of Matlab). DCT was preferred over Fast Fourier transform (FFT), ...
In the immediate vicinity of NGC 1316 these pathways appear to form extensions to the major axis of the main elliptical body of the galaxy. This major axis makes an angle of about 45掳 with the line joining the radio maxima. Further out the pathways curve sharply and enter the radio ...

The rotation curve of the edge-on disk galaxy NGC 5907 can be interpreted in terms of a two-component model, consisting of a truncated exponential disk and of a spherical halo. About 60% of the total mass inside the edge of the disk turns out to be in the halo. Indicative masses for...
