On an Expansion Method for Black Hole Quasinormal Modes and Regge Poles
Sam R. Dolan, Adrian C. Ottewill
We present a new method for determining the frequencies and wavefunctions of black hole quasinormal modes (QNMs) and Regge poles. The key idea is a novel ansatz for the wavefunctio…
Transport Equation Approach to Calculations of Hadamard Green functions and non-coincident DeWitt coefficients
Adrian C. Ottewill, Barry Wardell
Building on an insight due to Avramidi, we provide a system of transport equations for determining key fundamental bi-tensors, including derivatives of the world-function, σ(x,x'),…
Electromagnetic wave scattering by Schwarzschild black holes
Luís C. B. Crispino, Sam R. Dolan, Ednilton S. Oliveira
We analyze the scattering of a planar monochromatic electromagnetic wave incident upon a Schwarzschild black hole. We obtain accurate numerical results from the partial wave method…
Generating Electromagnetic Waves from Gravity Waves in Cosmology
P. A. Hogan, S. O'Farrell
Examples of test electromagnetic waves on a Friedmann-Lemaitre-Robertson-Walker(FLRW) background are constructed from explicit perturbations of the FLRW space-times describing grav…
Scattering of massless scalar waves by Reissner-Nordström black holes
Luis C. B. Crispino, Sam R. Dolan, Ednilton S. Oliveira
We present a study of scattering of massless planar scalar waves by a charged non-rotating black hole. Partial wave methods are applied to compute scattering and absorption cross s…
Scattering of Sound Waves by a Canonical Acoustic Hole
Sam R. Dolan, Ednilton S. Oliveira, Luís C. B. Crispino
This is a study of a monochromatic planar perturbation impinging upon a canonical acoustic hole. We show that acoustic hole scattering shares key features with black hole scatterin…
Pade Approximants of the Green Function in Spherically Symmetric Spacetimes
Marc Casals, Sam Dolan, Adrian Ottewill +1
We investigate the scalar Green function for spherically symmetric spacetimes expressed as a coordinate series expansion in the separation of the points. We calculate the series ex…
Self-Force Calculations with Matched Expansions and Quasinormal Mode Sums
Marc Casals, Sam R. Dolan, Adrian C. Ottewill +1
We present the first application of the Poisson-Wiseman-Anderson method of matched expansions, to compute the self-force acting on a point particle moving in a curved spacetime. Th…
