This article is an addendum to a recent publication by Chandra et al. [Phys. Rev. D 102, 044035 (2020)PRVDAQ2470-001010.1103/PhysRevD.102.044035]. We present updated results on upper limits on the merger of intermediate-mass black holes (IMBHs) with total mass between 210 M⊙ and 500 M⊙, mass ratio 1 to 7, and generic spins using data from the second Advanced LIGO observing run. Based on our analysis, we place the most stringent of our upper limits, of 0.28 Gpc-3 yr-1 on the merger rate density of precessing equal-mass intermediate-mass black holes with total masses of 210 M⊙.

“高级 LIGO 数据中一般自旋中等质量黑洞双星信号的数值相对性注入分析”附录

本文是 Chandra 等人最近发表的一篇文章的附录。[物理。修订版 D 102, 044035 (2020)PRVDAQ2470-001010.1103/PhysRevD.102.044035]。我们使用来自第二次高级 LIGO 观测运行的数据，提供了总质量在 210 M⊙ 和 500 M⊙ 之间、质量比为 1 到 7 和通用自旋的中等质量黑洞 (IMBH) 合并上限的最新结果。根据我们的分析，我们对总质量为 210 M⊙ 的进动等质量中等质量黑洞的合并率密度设置了最严格的上限，即 0.28 Gpc-3 yr-1。
