重子辅助的暗邦迪吸积与韦布空间望远镜“小红点”的起源

本文探讨了自相互作用暗物质晕的核区坍缩如何为早期宇宙中的超大质量黑洞提供种子。研究表明，该过程结合高效吸积能够解释韦布空间望远镜观测到的高红移“小红点”中黑洞的质量来源，并指出暗物质吸积在其中发挥了重要作用。

arXiv:2506.17641v2 Announce Type: replace Abstract: The gravothermal core collapse of self-interacting dark matter halos provides a mechanism for seeding supermassive black holes in the early Universe. 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.
