摘要

研究表明，这种暗物质的吸引力自相互作用可能会解决SMBH的大质量高角动量与其早期形成之间的矛盾。我们认为O(10-21) eV左右的超轻轴子DM是其起源，它也可能是最近观测到的纳赫兹随机引力波背景的原因。

Axion and the SuperMassive Black Holes at high z

Axion Dark Matter (DM) is studied on the formation of SuperMassive Black Holes (SMBH) at high red shift z. It is shown that the attractive self-interaction of this DM may resolve the tension between the large mass with high angular momentum of SMBH and its early time formation. We consider the ultra-light axion DM around $O (1 0^{- 21})$ eV as its origin, which may also cause nano-Hz stochastic gravitational wave background recently observed.
