A superradiance resonance cavity outside rapidly rotating black holes
Nils Andersson, Kostas Glampedakis
We discuss the late-time behaviour of a dynamically perturbed Kerr black hole. We present analytic results for near extreme Kerr black holes that show that the large number of virt…
Construction of Astrophysical Initial Data for Perturbations of Relativistic Stars
Nils Andersson, Kostas D. Kokkotas, Pablo Laguna +2
We develop a framework for constructing initial data sets for perturbations about spherically symmetric matter distributions. This framework facilitates setting initial data repres…
The inverse problem for pulsating neutron stars: A ``fingerprint analysis'' for the supranuclear equation of state
K. D. Kokkotas, T. A. Apostolatos, N. Andersson
We study the problem of detecting, and infering astrophysical information from, gravitational waves from a pulsating neutron star. We show that the fluid f and p-modes, as well as…
