Pseudospectrum and (in)stability of black hole total transmission modes
Yu-Sen Zhou, Ming-Fei Ji, Liang-Bi Wu +1
Total transmission modes (TTMs) are modes with complex frequencies that propagate across a black hole spacetime without reflection. Recently, it is found that suitably tailored tim…
Exceptional line and pseudospectrum in black hole spectroscopy
Li-Ming Cao, Ming-Fei Ji, Liang-Bi Wu +1
We investigate the exceptional points (EPs) and their pseudospectra in black hole perturbation theory. By considering a Gaussian bump modification to the Regge-Wheeler potential wi…

In Einstein-Gauss-Bonnet gravity, we study the quasi-normal modes (QNMs) of the tensor perturbation for the so-called Maeda-Dadhich black hole which locally has a topology $\mathca…
Constraint preserving boundary conditions in Bondi-Sachs gauge: a numerical study of stability of pure AdS spacetime
Li-Ming Cao, Liang-Bi Wu, Yu-Sen Zhou
In the Bondi-Sachs gauge, the Einstein equations with a cosmological constant coupled to a scalar field in spherical symmetry are cast into a first order strongly hyperbolic formul…
A Note on the Strong Hyperbolicity of Gravity with Dynamical Shifts
Li-Ming Cao, Liang-Bi Wu
The well-posedness of the gravitational equations of gravity are studied in this paper. Three formulations of the gravity with dynamical shifts (which are all based o…
A Bound on the Rate of Bondi Mass Loss
Li-Ming Cao, Long-Yue Li, Liang-Bi Wu
To ensure the light (emitted far away from the source of gravity) can arrive at the null infinity of an asymptotically flat spacetime, it is shown that the rate of Bondi mass aspec…
