Rainbow scattering of gravitational plane waves by a compact body
Tom Stratton, Sam R. Dolan
We study the time-independent scattering of a planar gravitational wave propagating in the curved spacetime of a compact body with a polytropic equation of state. We begin by consi…
Scattering from compact objects: Regge poles and the complex angular momentum method
Mohamed Ould El Hadj, Tom Stratton, Sam R. Dolan
We calculate the Regge poles of the scattering matrix for a gravitating compact body, for scalar fields and for gravitational waves in the axial sector. For a neutron-starlike body…
Spectral lines of extreme compact objects
Caio F. B. Macedo, Tom Stratton, Sam Dolan +1
We study the absorption of scalar fields by extreme/exotic compact objects (ECOs) -- horizonless alternatives to black holes -- via a simple model in which dissipative mechanisms a…
Rainbow scattering in the gravitational field of a compact object
Sam R Dolan, Tom Stratton
We study the elastic scattering of a planar wave in the curved spacetime of a compact object such as a neutron star, via a heuristic model: a scalar field impinging upon a spherica…
Series reduction method for scattering of planar waves by Kerr-Newman black holes
Tom Stratton, Luiz C. S. Leite, Sam R. Dolan +1
We present a practical method for evaluating the scattering amplitude that arises in the context of the scattering of scalar, electromagnetic and gravitational planar…
