论文摘要
通过计算涉及超级杂物黑洞（SMBH）的中间或极端质量比率合并引起的重力波（GW）信号，研究了激光干涉仪空间天线的多个准级（QN）模式，包括泛音和较高谐波的测量性。我们确认，快速旋转的黑洞的响声是长寿的，对于小质量比的合并而言，较高的响声量显着激发。我们研究了此类合并的QN模式的可测量性和可分离性，并证明了从快速旋转的SMBHS观察GWS具有检测超硫化QN模式并测试黑洞无发词定理的优势。
The measurability of multiple quasinormal (QN) modes, including overtones and higher harmonics, with the Laser Interferometer Space Antenna is investigated by computing the gravitational wave (GW) signal induced by an intermediate or extreme mass ratio merger involving a supermassive black hole (SMBH). We confirm that the ringdown of rapidly spinning black holes are long-lived, and higher harmonics of the ringdown are significantly excited for mergers of small mass ratios. We investigate the measurability and separability of the QN modes for such mergers and demonstrate that the observation of GWs from rapidly rotating SMBHs has an advantage for detecting superposed QN modes and testing the no-hair theorem of black holes.
