论文摘要
我们简要讨论了在前三个O1-O3运行期间由引力波观测器检测到的最突出的结果和特定来源，以及其形成的天体物理和宇宙学通道。我们表明，可以通过从环境培养基上吸收到原始二进制黑色孔之间的融合二元黑洞的有效自旋与组件的质量比之间观察到的相关性。我们还简要讨论了通过PULSAR时序阵列在纳米-Hz频带中搜索随机重力波背景的最新结果。
We briefly discuss the most prominent results and specific sources detected by gravitational-wave observatories LIGO-Virgo during first three O1-O3 runs, as well as possible astrophysical and cosmological channels of their formation. We show that it is possible to explain the observed correlation between the effective spin of coalescing binary black holes and mass ratio of the components by accretion from the ambient medium onto primordial binary black holes. We also briefly discuss the recent results of searches for stochastic gravitational-wave background in the nano-Hz frequency band by pulsar timing arrays.
