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.

早期宇宙中黑洞超大质量核的形成：标量-引力不稳定性机制。II.局部球形扰动的演变 ${}^{mathbf{1}}$$

摘要基于之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介质中的球形扰动理论以及此类模型的相似性，研究了早期宇宙中超大质量黑洞（SMBH）种子的形成。通过对这一过程的数值模拟，研究表明超大质量黑洞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。讨论了非线性对这一过程可能产生的影响。

期刊介绍： Gravitation and Cosmology is a peer-reviewed periodical, dealing with the full range of topics of gravitational physics and relativistic cosmology and published under the auspices of the Russian Gravitation Society and Peoplesâ€™ Friendship University of Russia. The journal publishes research papers, review articles and brief communications on the following fields: theoretical (classical and quantum) gravitation; relativistic astrophysics and cosmology, exact solutions and modern mathematical methods in gravitation and cosmology, including Lie groups, geometry and topology; unification theories including gravitation; fundamental physical constants and their possible variations; fundamental gravity experiments on Earth and in space; related topics. It also publishes selected old papers which have not lost their topicality but were previously published only in Russian and were not available to the worldwide research community
