论文摘要
在文献中,已提出紧凑型二元结合(CBC)是解释某些不重复快速无线电爆发(FRB)的起源的主要情况之一。 FRB和CBC事件率密度之间的巨大差异表明,它们的关联(如果有)最多应适用于一小部分FRB。通过贝叶斯估计方法,我们展示了FRB与CBC重力波(GW)事件的一致关联的统计分析如何检验这些关联的假设。我们表明,在高级LIGO的运行期间,$ \ sim100 $($ \ sim1000 $)的gw-nele grb frb具有分散度量(DM)值小于500 $ {\ rm pc〜cm^{ - 3}} $可能达到的约束可能会达到$ 10 \%$ $ $ $ $ $ $ $ $ $ $的约束(bb)。需要大于100 $ {\ rm pc〜cm^{ - 3}} $的DM值的FRB数量相同才能达到二进制中子星(BNS)合并的相同约束。通过对GW检测器的升级,可以以更少的FRB或更宽松的DM值来达到BBH和BNS合并的相同约束。也有可能对能够根据FRB和CBC的事件密度产生可观察到的FRB的每种类型的CBC的比例构成约束。这将进一步限制二进制BH系统中黑洞的无量纲电荷。
In the literature, compact binary coalescences (CBCs) have been proposed as one of the main scenarios to explain the origin of some non-repeating fast radio bursts (FRBs). The large discrepancy between the FRB and CBC event rate densities suggest their associations, if any, should only apply at most for a small fraction of FRBs. Through a Bayesian estimation method, we show how a statistical analysis of the coincident associations of FRBs with CBC gravitational wave (GW) events may test the hypothesis of these associations. We show that during the operation period of advanced LIGO, the detection of $\sim100$ ($\sim1000$) GW-less FRBs with dispersion measure (DM) values smaller than 500 ${\rm pc~cm^{-3}}$ could reach the constraint that less than $10\%$ (or $1\%$) FRBs are related to binary black hole (BBH) mergers. The same number of FRBs with DM values smaller than 100 ${\rm pc~cm^{-3}}$ is required to reach the same constraint for binary neutron star (BNS) mergers. With the upgrade of GW detectors, the same constraints for BBH and BNS mergers can be reached with less FRBs or looser requirements for the DM values. It is also possible to pose constraints on the fraction of each type of CBCs that are able to produce observable FRBs based on the event density of FRBs and CBCs. This would further constrain the dimensionless charge of black holes in binary BH systems.
