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…
Probing Ultralight Tensor Dark Matter with the Stochastic Gravitational-Wave Background from Advanced LIGO and Virgo's First Three Observing Runs
Rong-Zhen Guo, Yang Jiang, Qing-Guo Huang
Ultralight bosons are attractive dark-matter candidates and appear in various scenarios beyond standard model. They can induce superradiant instabilities around spinning black hole…
On the Interaction between Ultralight Bosons and Quantum-Corrected Black Holes
Rong-Zhen Guo, Chen Yuan, Qing-Guo Huang
Both ultralight dark matter and exploring the quantum nature of black holes are all topics of great interest in gravitational wave astronomy at present. The superradiant instabilit…
Tests for the existence of horizon through gravitational waves from a small binary in the vicinity of a massive object
Yun Fang, Rong-Zhen Guo, Qing-Guo Huang
In this letter we calculate the gravitational waves (GWs) emitted from a small binary (SB) by solving the Teukolsky equation in the background of a massive exotic compact object (E…
Near-horizon microstructure and superradiant instability of black holes
Rong-Zhen Guo, Chen Yuan, Qing-Guo Huang
Ultralight bosons, as important candidates of dark matter, can condense around spinning black holes (BHs) to form long-lived ``boson clouds'' due to superradiance instability. The…
