Effects of spacetime anisotropy on the galaxy rotation curves [PDF]

European Physical Journal C, 2013
The observations on galaxy rotation curves show significant discrepancies from the Newtonian theory. This issue could be explained by the effect of the anisotropy of the spacetime.

The Rotation Curve of our Galaxy

Applied Mechanics and Materials, 2014
The rotation curve of our Galaxy is derived from a large sample of objects with known radial velocities and distances. We collect data as completely as possible, especially the data with accurately measured trigonometric parallaxes. These observations are used to construct a highly accurate rotation curve of the Galaxy.

The Dynamics of Galaxy Rotational Curves

Space 2006, 2006
During the 1980’s, the first astronomical evidence was obtained that appeared to indicate spiral galaxies, (see Figure 1) do not rotate according to Newton’s’ Second Law of Motion: F=MA. The observations suggest that the outer stars in galaxies seem to rotate too fast for the amount of matter we see in the galaxy.

The Rotation Curve of the Galaxy

1983
The determination of the rotation curve of the Galaxy, θ(R), where θ is the circular velocity at galactocentric distance R, involves the synthesis of a large body of complementary (and sometimes contradictory) data. The synthesis has to be guided to some extent by theoretical considerations such as studying the distribution of mass in the Galaxy, i.e ...
