Galaxy rotation curves driven by massive vector fields: Key to the theory of the dark sector
Year: 2013
Type: article
Abstract: The nongauge vector field with as simple a Lagrangian as possible turned out to be an adequate tool for the macroscopic description of the main properties of dark matter. The dependence of the velocity of a star on the radius of the orbit $V(r)$---galaxy rotation curve---is derived analytically from the first principles completely within Einstein's general relativity. Milgrom's empirical modification of Newtonian dynamics in the nonrelativistic limit gets justified and specified in detail. In particular, the transition to a plateau is accompanied by damping oscillations. In the scale of a galaxy, and in the scale of the whole universe, the dark matter is described by a vector field with the same energy-momentum tensor. It is the evidence of the common physical nature. Now, when we have the general expression for the energy-momentum tensor of dark matter, it is possible to analyze its influence on the structure and evolution of superheavy stars and black holes.
