作为星系暗物质的单模双模引力和相干标量引力子场

Unimodular bimode gravity and the coherent scalar-graviton field as galaxy dark matter

Yu. F. Pirogov

摘要:

广义规范不变性/相对论的显式破坏被认为是引力性质的暗物质和暗能量的起源。违反当地的规模不变性单独,与剩余的么模,被认为是。除了四体积保持变形模式-横向张量引力子-度规包括一个压缩模式-标量引力子,或systolon。一致地给出了双模/标量张量引力的么模不变和广义协变度量理论。为了减少该理论的原始模糊性,施加了动力学全局对称性,并揭示了其随后的自发破缺。静态球对称的情况下,在空的,但可能的起源,空间进行了研究。构造了一个描述一种新的静态空间结构--暗空隙的三参数解。它具有引力禁闭的性质,在其外围具有对数引力势,并导致渐近平坦的转动曲线。暗陷隙是一个起源于黑洞中心的超大质量暗裂缝(标量修正的黑洞),周围环绕着一个核心暗晕。暗陷隙是星系的一个原型模型,它包含了对非引力物质分布和非球面性或旋转的最终解释。

英文摘要:

The explicit violation of the general gauge invariance/relativity is adopted as the origin of dark matter and dark energy of the gravitational nature. The violation of the local scale invariance alone, with the residual unimodular one, is considered. Besides the four-volume preserving deformation mode -- the transverse-tensor graviton -- the metric comprises a compression mode -- the scalar graviton, or the systolon. A unimodular invariant and general covariant metric theory of the bimode/scalar-tensor gravity is consistently worked out. To reduce the primordial ambiguity of the theory a dynamical global symmetry is imposed, with its subsequent spontaneous breaking revealed. The static spherically symmetric case in the empty, but possibly for the origin, space is studied. A three-parameter solution describing a new static space structure -- the dark lacuna -- is constructed. It enjoys the property of gravitational confinement, with the logarithmic potential of gravitational attraction at the periphery, and results in the asymptotically flat rotation curves. Comprising a super-massive dark fracture (a scalar-modified black hole) at the origin surrounded by a cored dark halo, the dark lacunas are proposed as a prototype model of galaxies, implying an ultimate account for the distributed non-gravitational matter and a putative asphericity or rotation.
