旋转黑洞的宇宙膨胀

Cosmic expansion from spinning black holes

John T. Giblin, James B. Mertens, Glenn D. Starkman, Chi Tian

摘要:

我们研究宇宙膨胀如何在包含旋转黑洞晶格的宇宙中产生。我们研究了平均膨胀性质随黑洞基本性质的变化,包括黑洞的裸质量和黑洞的自旋。然后,我们探讨如何密切的膨胀属性对应于相应的物质主导的FLRW宇宙的属性。作为剩余辐射存在于初始数据衰减,我们发现很好的协议与物质为主的FLRW解决方案,和体积中的有效密度是很好地描述了由视界质量的黑洞。

英文摘要:

We examine how cosmological expansion arises in a universe containing a lattice of spinning black holes. We study averaged expansion properties as a function of fundamental properties of the black holes, including the bare mass of the black holes and black hole spin. We then explore how closely the expansion properties correspond to properties of a corresponding matter-dominated FLRW universe. As residual radiation present in the initial data decays, we find good agreement with a matter-dominated FLRW solution, and the effective density in the volume is well-described by the horizon mass of the black hole.
