Gravitational Wave Tails and Transient Behaviors of Quantum-Corrected Black Holes
Rong-Zhen Guo, Qing-Guo Huang
Gravitational wave astronomy plays a pivotal role in testing the dynamics of gravity in strong-field regimes and probing the nature of black holes. Motivated by recent studies on l…

Metric Reconstruction and Second Order Perturbation for Generic Spherically Symmetric spacetime
Rong-Zhen Guo, Qing-Guo Huang
Higher-order perturbations during the ringdown phase are essential for testing gravitational theories. This requires a perturbation framework that extends beyond General Relativity…

Generic Modified Teukolsky Formalism beyond General Relativity for Spherically Symmetric Cases
Rong-Zhen Guo, Hongwei Tan, Qing-Guo Huang
The observation of gravitational waves has inaugurated a new era for testing gravitational theories in strong-field, nonlinear regimes. Gravitational waves emit during the ringdown…
