Real-time Gravitational Wave Response in Thermal Spinning fields
Atsuhisa Ota, Hui-Yu Zhu, Yuhang Zhu
We study how the spin content of the thermal plasmas affects the propagation of gravitational waves in a radiation-dominated universe. As a simple but representative setup, we cons…
Quantum Treatment of Black Hole Superradiance
Lingyun Fu, Hidetoshi Omiya, Takahiro Tanaka +3
Rotating black holes can form dense boson clouds through superradiant instability, making Kerr black holes a powerful probe of ultralight massive bosons. Previous studies of black…
Survival of the Fittest: Testing Superradiance Termination with Simulated Binary Black Hole Statistics
Hui-Yu Zhu, Xi Tong, Giorgio Manzoni +1
The superradiance instability of rotating black holes leads to the formation of an ultralight boson cloud with distinctive observational signatures, making black holes an effective…
Modulating binary dynamics via the termination of black hole superradiance
Kaiyuan Fan, Xi Tong, Yi Wang +1
A superradiant cloud of ultralight bosons near a rotating black hole provides a smoking gun for particle physics in the infrared. However, tidal perturbations from a nearby binary…
