论文摘要
在重力波中检测到的中性星际黑洞（NSBH）合并有可能阐明超新星物理学，状态密集的物质方程以及为潜在电磁对应物提供动力的天体物理过程。我们使用迄今为止在重力波中检测到的四个候选NSBH事件的人口，以虚假警报率$ \ leq 1〜 \ mathrm {yr}^{ - 1} $来限制这些系统的质量和旋转分布以及旋转分布以及多中途的前景。我们发现，NSBH中的黑洞比黑洞二进制文件的旋转既不那么大，并且无量纲的旋转较小。我们还发现证据表明，最大的中子星和NSBHS中最小的黑洞之间存在质量差距，信誉为98.6％。使用由重力波数据而不是二进制模拟驱动的方法，我们发现在重力波中可检测到的NSBH合并中不到14％将具有电磁对应物。尽管具有对应方的质量差距和源源的一部分的存在取决于事件的选择和源分类的先验知识，但与黑洞二进制文件中NSBHS中的黑洞具有较低的质量和更小的自旋参数的结论是强大的。最后，我们提出了一种基于电磁对应物的非探测，对NSBH合并进行多通电者分析的方法，并得出结论，即使在最乐观的情况下，也可以通过多中心符号的NSBH检测获得的中子星方程的约束也不是从Gration-Grattiartial Wiles Merivil tormentiar tormiartiar torniartion triantiar niment in triential niment in triential niment in triential nimentiral niment in sativer in native sation in native，观察。
Neutron star-black hole (NSBH) mergers detected in gravitational waves have the potential to shed light on supernova physics, the dense matter equation of state, and the astrophysical processes that power their potential electromagnetic counterparts. We use the population of four candidate NSBH events detected in gravitational waves so far with a false alarm rate $\leq 1~\mathrm{yr}^{-1}$ to constrain the mass and spin distributions and multimessenger prospects of these systems. We find that the black holes in NSBHs are both less massive and have smaller dimensionless spins than those in black hole binaries. We also find evidence for a mass gap between the most massive neutron stars and least massive black holes in NSBHs at 98.6% credibility. Using an approach driven by gravitational-wave data rather than binary simulations, we find that fewer than 14% of NSBH mergers detectable in gravitational waves will have an electromagnetic counterpart. While the inferred presence of a mass gap and fraction of sources with a counterpart depend on the event selection and prior knowledge of source classification, the conclusion that the black holes in NSBHs have lower masses and smaller spin parameters than those in black hole binaries is robust. Finally, we propose a method for the multimessenger analysis of NSBH mergers based on the nondetection of an electromagnetic counterpart and conclude that, even in the most optimistic case, the constraints on the neutron star equation of state that can be obtained with multimessenger NSBH detections are not competitive with those from gravitational-wave measurements of tides in binary neutron star mergers and radio and X-ray pulsar observations.
