双超大质量黑洞的引力波辐射

Gravitational wave emission from binary supermassive black holes

A. Sesana

摘要:

大质量黑洞双星(MBHB)是等级结构形成过程中不可避免的产物,根据广义相对论,MBHB被认为是宇宙中最强的引力波源。在这篇文章中,我提供了一个广泛的概述MBHB作为GW源。在回顾了GW发射的基础知识从二进制系统和MBHB的形成,演化和动力学,我描述了一些细节之间的连接二进制属性和发射的引力波形。直接GW观测将提供有关这些极端物体的物理性质和天体物理特性的前所未有的丰富信息,从而能够重建它们的宇宙历史,动力学以及与其致密恒星和气体环境的耦合。在这种情况下,我描述了正在进行的和未来的努力,使直接检测与空间为基础的干涉测量和脉冲星定时阵列,突出了宝贵的科学支出,这样的企业。

英文摘要:

Massive black hole binaries (MBHBs) are unavoidable outcomes of the hierarchical structure formation process, and according to the theory of general relativity are expected to be the loudest gravitational wave (GW) sources in the Universe. In this article I provide a broad overview of MBHBs as GW sources. After reviewing the basics of GW emission from binary systems and of MBHB formation, evolution and dynamics, I describe in some details the connection between binary properties and the emitted gravitational waveform. Direct GW observations will provide an unprecedented wealth of information about the physical nature and the astrophysical properties of these extreme objects, allowing to reconstruct their cosmic history, dynamics and coupling with their dense stellar and gas environment. In this context I describe ongoing and future efforts to make a direct detection with space based interferometry and pulsar timing arrays, highlighting the invaluable scientific payouts of such enterprises.
