Revisiting environmental effects on black hole quasibound-state spectra with relativistic perturbation theory
Yin-Da Guo, Qi-Xuan Xu, Richard Brito +1
We present a relativistic framework for computing corrections to the eigenfrequency spectrum of a massive scalar field in perturbed black-hole spacetimes, including first-order shi…
Local Group Velocity Distribution inside Superradiant Condensates
Yin-Da Guo, Kai-Dong Zhou, Shou-Shan Bao +1
Superradiance enables scalar fields to extract energy and angular momentum from a rotating black hole (BH), leading to the formation of a BH-condensate system. Previous studies mai…
Effect of accretion on scalar superradiant instability
Yin-Da Guo, Shou-Shan Bao, Tianjun Li +1
Superradiance can lead to the formation of a black hole (BH) condensate system. We thoroughly investigate the accretion effect on the evolution of this system, and the gravitationa…
Evolution and detection of vector superradiant instabilities
Yin-Da Guo, Nayun Jia, Shou-Shan Bao +2
Ultralight vectors can extract energy and angular momentum from a Kerr black hole (BH) due to superradiant instability, resulting in the formation of a BH-condensate system. In thi…
