论文摘要
In this paper, we forecast the expected detection rates and redshift distributions of gravitationally lensed gravitational waves (GWs) from three different mass distributions of primordial black holes (PBHs) and two stellar formation models of astrophysical black holes (ABHs) in the context of DECi-hertz Interferometer Gravitational wave Observatory (DECIGO) and it's smaller scale version B-DECIGO.这表明Decigo每年都能从此类二进制黑洞（BBHS）中检测到$ 10^4-10^5 $ GW信号，并且PBHS的事件率分布与ABH的事件率分布不同，因为它们的合并率相对于红移。大量的事件率使$ 5-100 $ $ the的GW信号的检测可能是可能的。在考虑了重力镜头效应之后，PBHS和ABH的检测率和分布之间的差异将更加重要。因此，这可以用作将PBH与ABH区分开的补充方法。
In this paper, we forecast the expected detection rates and redshift distributions of gravitationally lensed gravitational waves (GWs) from three different mass distributions of primordial black holes (PBHs) and two stellar formation models of astrophysical black holes (ABHs) in the context of DECi-hertz Interferometer Gravitational wave Observatory (DECIGO) and it's smaller scale version B-DECIGO. It suggests that DECIGO will be able to detect $10^4-10^5$ GW signals from such binary black holes (BBHs) each year and the event rate distributions for PBHs will differ from those for ABHs due to their different merger rate with respect to redshift. The large number of event rates make $5-100$ detections of lensed GW signals being possible. After considering the gravitational lensing effect, the difference between the detection rates and distributions for PBHs and ABHs will be more significant. Therefore, this can be served as a complementary method to distinguish PBHs from ABHs.
