We show that the collapse of a small fraction of the halo mass can trigger general-relativistic instability and produce black hole seeds in halos with masses $\\gtrsim10^{9}{\\rm\\,M_\\odot}$ at high redshift. We investigate whether this process can account for the origin of JWST little red dots at $z\\sim4-11$, which host black holes with masses $\\sim10^7{\\rm\\,M_\\odot}$. We find that such masses can be reached within $\\sim500{\\rm\\,Myr}$ through rapid core collapse followed by efficient accretion, even for initial seed masses of $1-10^3{\\rm\\,M_\\odot}$. This scenario allows a substantial fraction of the black hole mass to originate from dark matter accretion, potentially offering a viable pathway to forming massive black holes at high redshift.","url_abs":"https://arxiv.org/abs/2506.17641v1","url_pdf":"https://arxiv.org/pdf/2506.17641v1.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"links_only","authors_date_abstract":"arXiv metadata, CC0 1.0 (https://info.arxiv.org/help/license), from the Kaggle arXiv metadata snapshot of 2026-09-12"},"code_links":[{"paper_slug":"dark-bondi-accretion-aided-by-baryons-and-the","repo_url":"https://github.com/ymzhong/gravothermal","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":1,"framework":"none","reach":null}],"tasks":[],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"syntology_url":null,"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
