论文摘要

随着引力波天文学的出现,从黑洞(BHS)中寻找引力波回声正在成为对其近距离的量子性质的有趣探测。新生儿BHS可能是回声的强烈发射器,因为它们在编队时伴随着周围时空的大扰动。利用量子黑洞地震学框架(Oshita等,2020),我们研究了由中子星星合并和失败超新星产生的BH形成时的预期回波。对于来自中子星合并的BH残留物,我们评估了这些模型的一致性,最新声称是在中子星合并事件GW170817之后的回声。我们发现,GW170817中声称的回声(如果是真实的话)表明,泛音在残余BH的回合中贡献了大量能量。我们最终讨论了通过第二代和第三代重力波检测器从失败的超新星中回波的可检测性,并发现当前(未来)检测器限制了在几个MPC(几个x 10 MPC)内发生的事件的物理反射率模型。检测此类回声信号可能会显着限制中子恒星状态的最大质量和方程。

With the advent of gravitational wave astronomy, searching for gravitational wave echoes from black holes (BHs) is becoming an interesting probe of their quantum nature near their horizons. Newborn BHs may be strong emitters of echoes, as they accompany large perturbations in the surrounding spacetime upon formation. Utilizing the Quantum Black Hole Seismology framework (Oshita et al. 2020), we study the expected echoes upon BH formation resulting from neutron star mergers and failed supernovae. For BH remnants from neutron star mergers, we evaluate the consistency of these models with the recent claim on the existence of echoes following the neutron star merger event GW170817. We find that the claimed echoes in GW170817, if real, suggest that overtones contribute a significant amount of energy in the ringdown of the remnant BH. We finally discuss the detectability of echoes from failed supernovae by second and third-generation gravitational wave detectors, and find that current (future) detectors constrain physical reflectivity models for events occurring within a few Mpc (a few x 10 Mpc). Detecting such echo signals may significantly constrain the maximum mass and equation of state of neutron stars.
