LIGO时代的黑洞准正规模

Black hole quasinormal modes in the era of LIGO

Cecilia Chirenti

摘要:

经过漫长的等待,引力波天文学终于开始了。二元黑洞合并正在被LIGO和Virgo探测到,理论家们开始收到大量需要分析的数据。在这一点上,我们终于可以开始测试引力的替代理论和紧凑物体的不同模型。一个强有力的工具是背景时空的微扰分析。本文从线性微扰理论出发,简要介绍了黑洞准正规模的概念和分析方法,并简要讨论了最近探测到的引力波信号的数值计算方法和天体物理意义。有了这些基本成分,更复杂的分析和应用是可能的。

英文摘要:

After a long wait, gravitational wave astronomy has finally begun. Binary black hole mergers are being detected by LIGO and Virgo, and theorists are starting to receive a wealth of data to be analized. At this point we can at long last begin to test alternative theories of gravity and different models of compact objects. One powerful tool to do this is the perturbative analysis of background spacetimes. The objective of this brief review is to introduce the notion and analysis of black hole quasinormal modes, starting from the linear perturbation theory and including a brief discussion of numerical methods and astrophysical implications in the gravitational wave signals recently detected. With these basic ingredients, more sophisticated analyses and applications are possible.
