论文摘要
最近，Graham等。 （2020）将ZTF19ABANRHR确定为二进制黑洞合并GW190521的候选电磁对应物。作者认为，观察结果与踢的二进制黑洞与激活银河核Agn J124942.3+344929相互作用的踢二进制黑洞一致。如果真正的关联（而不是偶然的关联），这对Ligo/处女座二元合并的来源，电磁对应物的未来前景以及宇宙膨胀率的测量都具有影响。在这封信中，我们基于本地化重叠提供了对多通间的重合意义的重新分析，并发现GW190521和ZTF19ABANRHR的常见来源的几率取决于使用的波形模型在1到12之间。我们认为这种不足的证据保证将GW190521与ZTF19ABANRHR相关联。
Recently, Graham et al. (2020) identified ZTF19abanrhr as a candidate electromagnetic counterpart to the binary black hole merger GW190521. The authors argue that the observations are consistent with a kicked binary black hole interacting with the accretion disk of the activate galactic nucleus AGN J124942.3+344929. If a real association (rather than happenstance), this has implications for the sources of LIGO/Virgo binary mergers, future prospects for electromagnetic counterparts, and measurements of the expansion rate of the Universe. In this Letter, we provide a re-analysis of the multi-messenger coincidence significance based on the localisation overlap and find that that the odds of a common source for GW190521 andZTF19abanrhr range between 1 and 12 depending on the waveform model used; we consider this insufficient evidence to warrant confidently associating GW190521 with ZTF19abanrhr.
