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…
