- Title
Axion and the SuperMassive Black Holes at high z.
- Authors
Fukuyama, Takeshi
- Abstract
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 − 2 1) eV as its origin, which may also cause nano-Hz stochastic gravitational wave background recently observed.
