摘要
坍缩黑洞被暗物质包围的平衡静态的可能性,使我们有可能理解星系外围恒星平直旋转曲线的存在。在主导引力作用下,玻色-爱因斯坦凝聚态是极度压缩黑洞在能量上最有利的状态。事实证明,纵向矢量场作为一种波函数,能够充分描述观测到的暗物质表现。以基本粒子标准模型中的 Z、W 和 H 玻色子的凝聚态(静止能量为 100 GeV)为例,研究了恒星的旋转曲线与星系中心黑洞质量的关系。在黑洞质量与太阳质量(2 ×1033 g)相当的情况下,暗物质对引力场的贡献占主导地位。在这种情况下,星系旋转曲线上的高原就得到了明确的表达。随着黑洞质量的增加,暗物质对引力的贡献减少,而黑洞的贡献增加。银河系中心黑洞的质量比太阳质量大七个数量级。黑洞对引力的贡献占主导地位。因此,在我们的银河系中,恒星的旋转速度(V\left( r \right)\)作为半径的函数,与\({1\mathord{\left/ {\vphantom {1 {\sqrt r }}} 成比例地减小。\right.\kern-0em}({sqrt r }})符合牛顿定律。
Mutual Dependence between a Bosonic Black Hole and Dark Matter and the Explanation of Asymptotically Flat Galaxy Rotation Curves
The possibility of an equilibrium static state of a collapsed black hole, surrounded by dark matter, makes it possible to understand the existence of flat rotation curves of stars on the periphery of a galaxy. Under the dominant gravity, a Bose–Einstein condensate is the energetically most favourable state of an extremely compressed black hole. It turned out that the longitudinal vector field, as a wave function, adequately describes the observed manifestations of dark matter. Considering as an example a condensate of Z, W, and H bosons of the Standard Model of Elementary Particles (with rest energy of the order of 100 GeV), the dependence of rotation curves of stars on the mass of a black hole at the galaxy center was investigated. With this composition of the black hole of a mass on the order of the solar mass (2 ×1033 g), the dark matter gives the dominant contribution to the gravitational field. In this case, the plateau on the galaxy rotation curve is explicitly expressed. As the black hole mass increases, a contribution to the gravity from the dark matter decreases, while a contribution from the black hole increases. The mass of the black hole at the center of the Milky Way galaxy is seven orders of magnitude greater than the solar mass. The contribution to the gravity from the black hole dominates. Therefore, in our galaxy, the rotation velocity of stars \(V\left( r \right)\) as a function of radius decreases in proportion to \({1 \mathord{\left/ {\vphantom {1 {\sqrt r }}} \right. \kern-0em} {\sqrt r }}\) in accordance with Newton’s law.
期刊介绍:
The journal Fizika Elementarnykh Chastits i Atomnogo Yadr of the Joint Institute for Nuclear Research (JINR, Dubna) was founded by Academician N.N. Bogolyubov in August 1969. The Editors-in-chief of the journal were Academician N.N. Bogolyubov (1970–1992) and Academician A.M. Baldin (1992–2001). Its English translation, Physics of Particles and Nuclei, appears simultaneously with the original Russian-language edition. Published by leading physicists from the JINR member states, as well as by scientists from other countries, review articles in this journal examine problems of elementary particle physics, nuclear physics, condensed matter physics, experimental data processing, accelerators and related instrumentation ecology and radiology.
