Spectral method for metric perturbations of black holes: Kerr background case in general relativity
Adrian Ka-Wai Chung, Pratik Wagle, Nicolas Yunes
We present a novel approach, (METRICS), to calculate the gravitational metric perturbations and the quasinormal-mode frequenci…
Perturbations of spinning black holes in dynamical Chern-Simons gravity I. Slow rotation equations
Pratik Wagle, Dongjun Li, Yanbei Chen +1
The detection of gravitational waves resulting by the LIGO-Virgo-Kagra collaboration has inaugurated a new era in gravitational physics, providing an opportunity to test general re…
Isospectrality breaking in the Teukolsky formalism
Dongjun Li, Asad Hussain, Pratik Wagle +3
General relativity, though the most successful theory of gravity, has been continuously modified to resolve its incompatibility with quantum mechanics and explain the origin of dar…
Spectral Method for the Gravitational Perturbations of Black Holes: Schwarzschild Background Case
Adrian Ka-Wai Chung, Pratik Wagle, Nicolas Yunes
We develop a novel technique through spectral decompositions to study the gravitational perturbations of a black hole, without needing to decouple the linearized field equations in…
