摘要

原始黑洞（PBHs）初始空间分布中的泊松噪声导致了它们在早期宇宙中的活跃聚类。使用一个简单的模型，这项工作检查了星团的内部动力学，双黑洞的形成和它们的合并。结果表明，与星系团中的PBH合并相比，在辐射主导阶段形成的PBH双星受到积极扰动，对引力波事件的贡献较小。

Primordial Black Hole Binaries: The Impact of Poisson Clustering

Poisson noise in the initial spatial distribution of primordial black holes (PBHs) leads to their active clustering in the early Universe. Using a simple model, this work examines the internal dynamics of clusters, the formation of binary black holes and their mergers. It is shown that PBH binaries formed at the radiation-dominated phase are actively perturbed and make a subdominant contribution to gravitational wave events compared to PBHs mergers in clusters.

期刊介绍： The journal Fizika Elementarnykh Chastits i Atomnogo Yadr of the Joint Institute for Nuclear Research (JINR, Dubna) was founded by Academician N.N. Bogolyubov in August 1969. The Editors-in-chief of the journal were Academician N.N. Bogolyubov (1970–1992) and Academician A.M. Baldin (1992–2001). Its English translation, Physics of Particles and Nuclei, appears simultaneously with the original Russian-language edition. Published by leading physicists from the JINR member states, as well as by scientists from other countries, review articles in this journal examine problems of elementary particle physics, nuclear physics, condensed matter physics, experimental data processing, accelerators and related instrumentation ecology and radiology.
