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…

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…
