利用天琴研究引力与黑洞本质

Probing the nature of gravity and black hole with TianQin

空间引力波探测器的一个重要研究目标,是利用引力波信号对物理学的基本理论进行研究。具体而言,主要是研究引力与黑洞的本质。前者主要是检验引力理论是否符合广义相对论,后者则是检验探测到的辐射引力波的致密天体是否为广义相对论中所预言的克尔黑洞。天琴作为一个空间引力波探测器,将能够探测到大量不同类型的引力波源所发出的信号。利用这些各不相同的信号,我们将有望从各个可能的方面对引力与黑洞的本质进行研究。在本文中,我们将对天琴所采用的研究引力与黑洞本质的方法进行介绍,并对预期中天琴所能达到的探测精度进行分析。

An important objective of space borne gravitational wave detectors is using gravitational wave signals to probe the fundamental theories of physics.Specifically,it means the study of the nature of gravity and black holes.The former objective is to test whether the gravitational theory is general relativity or not,and the latter one is to test whether the detected compact obejcts radiating gravitational waves is the Kerr black hole predicted in general relativity.As a space borne gravitational wave detector,TianQin may detect a lot of signals from many different kinds of gravitational wave sources.Using these signals,we expect to probe the nature of gravity and black holes from all possible aspects.In this article,we will introduce the methods that TianQin would use to probe the nature of gravity and black holes,and analyze the expected detection accuracy of TianQin.
