An article published in “The Astrophysical Journal Letters” reports a model of supermassive black hole formation that explains the rapid growth of the ones observed in the early universe. Wei-Xiang Feng, Hai-Bo Yu, and Yi-Ming Zhong propose a model in which the so-called seeds from which these gigantic black holes are formed are generated by a halo of self-interacting dark matter. According to this model, the collapse that forms the seed is accelerated by baryonic matter, common matter, a unified scenario between the two types of matter.
