Abstract

Based on the previously formulated theory of spherical perturbations in the cosmological medium of self-gravitating scalarly charged fermions with the Higgs scalar interaction and the similarity properties of such models, the formation of supermassive black hole (SMBH) seeds in the early Universe is studied. Using numerical simulation of the process, it is shown that the mass of SMBH seeds during the evolution process reaches a limiting value, after which it begins to slowly fall. The possible influence of nonlinearity on this process is discussed.

摘要

基于先前提出的具有希格斯标量相互作用的自引力标量带电费米子宇宙学介质中的球形摄动理论以及此类模型的相似性质，研究了早期宇宙中超大质量黑洞（SMBH）种子的形成。通过对该过程的数值模拟表明，SMBH种子的质量在演化过程中达到一个极限值，之后开始缓慢下降。讨论了非线性对此过程的可能影响。
