Curvature Reconstruction and Tensor Polarizations in Isospectrality-Breaking Black-Hole Perturbations
Pratik Wagle, Dongjun Li, Yanbei Chen +1
Testing general relativity with the ringdown phase of gravitational waves requires connecting modifications of black-hole perturbation dynamics to observable signatures in detector…
Parity Isospectrality of the Kerr--Newman--de Sitter Black Hole
Colin Weller, Dongjun Li, Pratik Wagle +2
Vacuum Kerr perturbations in general relativity have identical even- and odd-parity quasinormal frequencies. We establish this parity isospectrality for linear gravitoelectromagnet…
Chiral symmetry and black hole isospectrality
Colin Weller, Dongjun Li, Pratik Wagle +3
We prove that black-hole isospectrality between linearly independent solutions follows whenever radiative metric and matter perturbations are reconstructed from complex master vari…
Beyond Three Terms: Continued Fractions for Rotating Black Holes in Modified Gravity
Georgios Karikos, Jayana A. Saes, Pratik Wagle +1
Black-hole ringdown offers a clean probe of strong gravity, but one of its most accurate tools--Leaver's continued-fraction method--requires a three-term recurrence relation. Beyon…
Modified Teukolsky formalism: Null testing and numerical benchmarking
Fawzi Aly, Mahmoud A. Mansour, Luis Lehner +3
Next-generation gravitational-wave detectors will make black-hole ringdown an increasingly sensitive probe of small departures from General Relativity in the strong-field regime. T…
Perturbations of spinning black holes in dynamical Chern-Simons gravity: Slow rotation quasinormal modes
Dongjun Li, Pratik Wagle, Yanbei Chen +1
Gravitational waves offer new ways to test general relativity (GR) in the strong-field regime, including tests involving the ringdown phase of binary black hole mergers, characteri…
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…
Perturbations of spinning black holes beyond General Relativity: Modified Teukolsky equation
Dongjun Li, Pratik Wagle, Yanbei Chen +1
The detection of gravitational waves from compact binary mergers by the LIGO/Virgo collaboration has, for the first time, allowed for tests of relativistic gravity in the strong, d…
Quasinormal modes of slowly-rotating black holes in dynamical Chern-Simons gravity
Pratik Wagle, Nicolas Yunes, Hector O. Silva
The detection of gravitational waves from compact binary mergers by the LIGO/Virgo collaboration has, for the first time, allowed us to test relativistic gravity in its strong, dyn…
Polarization modes of gravitational waves in Quadratic Gravity
Pratik Wagle, Alexander Saffer, Nicolas Yunes
The observation of the inspiral and merger of compact binaries by the LIGO-Virgo collaboration has allowed for new tests of Einstein's theory in the extreme gravity regime, where g…
Hair loss in parity violating gravity
Pratik Wagle, Nicolas Yunes, David Garfinkle +1
The recent detection of gravitational waves by the LIGO/VIRGO collaboration has allowed for the first tests of Einstein's theory in the extreme gravity regime, where the gravitatio…
