论文摘要
引力波实验发现了异常的黑洞质量，对这些黑洞的起源提出了基本问题。质量小于chandrasekhar限制$ \ of1.4 \，m_ \ odot $的黑孔基本上不可能通过恒星进化产生。我们提出了一个新的频道，用于生产低质量黑洞的新渠道：恒星物体会灾难性地积聚无吹式暗物质，然后小的深色核心随后倒塌，吞噬了宿主星并将其传输到黑洞中。允许的深色物质质量范围很大，有效的Chandrasekhar极限较小，因此质量较小。我们指出了几种测试我们的建议的途径，重点是合并率的红移依赖性。我们表明，合并速率的红移依赖性可以用作低质量黑洞的透射起源的探针。
Unusual masses of black holes being discovered by gravitational wave experiments pose fundamental questions about the origin of these black holes. Black holes with masses smaller than the Chandrasekhar limit $\approx1.4\,M_\odot$ are essentially impossible to produce through stellar evolution. We propose a new channel for production of low mass black holes: stellar objects catastrophically accrete non-annihilating dark matter, and the small dark core subsequently collapses, eating up the host star and transmuting it into a black hole. The wide range of allowed dark matter masses allows a smaller effective Chandrasekhar limit, and thus smaller mass black holes. We point out several avenues to test our proposal, focusing on the redshift dependence of the merger rate. We show that redshift dependence of the merger rate can be used as a probe of the transmuted origin of low mass black holes.
