Self-interaction effects on the Kerr black hole superradiance and their observational implications
Ning Xie, Fa Peng Huang
Through the black hole (BH) superradiance, ultralight bosons can form dense clouds around rotating Kerr BHs. Certain ultralight bosons, such as axions and axion-like particles (pro…

Implication of nano-Hertz stochastic gravitational wave background on ultralight axion particles
Jing Yang, Ning Xie, Fa Peng Huang
Recently, the Hellings Downs correlation has been observed by different pulsar timing array (PTA) collaborations, such as NANOGrav, European PTA, Parkes PTA, and Chinese PTA. These…

Imprints of ultralight axions on the gravitational wave and pulsar timing measurement
Ning Xie, Fa Peng Huang
The axion or axion-like particle motivated from a natural solution of strong CP problem or string theory is a promising dark matter candidate. We study the new observational effect…
