用Fokker-Planck方法研究原初黑洞团的演化
Evolution of the cluster of primordial black holes within the Fokker-Planck approach
摘要：
在忽略气体对黑洞吸积的情况下，利用Fokker-Planck方程计算了原始黑洞团的演化.此外，我们还考虑了位于星团中心的大质量黑洞对星团演化的影响。尽管它在星系团的中心区域产生了额外的势能，并可能捕获周围的黑洞，但对于1 Gyr，中心黑洞的增长率可以忽略不计。此外，我们发现一个显着的（约10倍）扩大集群。
英文摘要：
The calculation results of the evolution of the cluster of primordial black holes based on the Fokker-Planck equation with neglecting of the gas accretion onto black holes are presented. In addition, we consider how a massive black hole located within the cluster center affects on its evolution. Despite it creates an additional potential in the central region of the cluster and might capture surrounding black holes, a negligible growth rate of a central black hole was shown for 1 Gyr. Furthermore, we find a significant (approximately tenfold) expansion of the cluster.
