Description
Sunmyon Chon, Shingo Hirano, Tomoaki Ishiyama, Seok-Jun Chang, and Volker Springel run cosmic simulations of how huge black holes form. Their paper is from two thousand twenty-six. New space telescope data show far more over-heavy black holes in young galaxies than models had made. How they grew so fast was not clear.
Their runs follow birth and growth in dense early clusters, with radiation and fluid flow both in play. Heavy seeds form on their own, larger than most past guesses. Thick disks around them scatter light and give the broad glow seen in the so-called little red dots. Fast feeding then grows the holes a lot in a short span. The dots may be a brief, veiled stage of seed growth.
