论文摘要
如果将恒星质量黑洞嵌入到极度密集且巨大的分子云中，并且相对于环境培养基长时间，则可以通过Bondi积聚显着生长其质量。这为形成巨大的恒星质量黑洞提供了一个新颖而又具有挑战性的渠道。我们讨论了该通道如何解释Ligo/Pirgo重力波检测器以及声称的大量黑洞候选LB-1所观察到的大规模二进制黑洞合并系统GW190521。
A stellar mass black hole can grow its mass noticeably through Bondi accretion, if it is embedded in an extremely dense and massive molecular cloud with slow motion with respect to the ambient medium for an extended period of time. This provides a novel, yet challenging channel for the formation of massive stellar-mass black holes. We discuss how this channel may account for the massive binary black hole merger system GW190521 as observed by LIGO/Virgo gravitational wave detectors as well as the claimed massive black hole candidate LB-1.
