Massive Black Holes Seeded by Dark Matter — Implications for Little Red Dots and Gravitational Wave Signatures

Tingwei Shen, Xuejian Shen, Huangyu Xiao, Mark Vogelsberger, Fangzhou Jiang | Summary: [[{“value”:”Observations of supermassive black holes (SMBHs) at high redshifts challenge standard seeding scenarios. We examine a dissipative self-interacting dark matter (dSIDM) model in which gravothermal collapse leads to the formation of massive BH seeds ab initio. We utilize a semi-analytical framework to predict […]
