致密天体聚并率

Rates of Compact Object Coalescences

Ilya Mandel, Floor S. Broekgaarden

摘要:

引力波探测使得能够测量由两个致密物体-中子星和/或黑洞-组成的双星的合并速度。包含中子星的双星的合并速率进一步受到电磁观测的限制,包括银河射电双星和短伽马射线暴。与此同时,越来越复杂的紧凑物体通过各种进化渠道合并的模型产生了一系列理论上预测的速率。仪器灵敏度的快速提高,以及新的和改进的调查计划,使这是一个适当的时间来总结现有的观测和理论知识的紧凑的二进制合并率。

英文摘要:

Gravitational-wave detections are enabling measurements of the rate of coalescences of binaries composed of two compact objects -- neutron stars and/or black holes. The coalescence rate of binaries containing neutron stars is further constrained by electromagnetic observations, including Galactic radio binary pulsars and short gamma-ray bursts. Meanwhile, increasingly sophisticated models of compact objects merging through a variety of evolutionary channels produce a range of theoretically predicted rates. Rapid improvements in instrument sensitivity, along with plans for new and improved surveys, make this an opportune time to summarise the existing observational and theoretical knowledge of compact-binary coalescence rates.
