Gravitational-wave glitches: resonant islands and frequency jumps in non-integrable extreme-mass-ratio inspirals
Kyriakos Destounis, Kostas D. Kokkotas
The detection of gravitational waves from extreme-mass-ratio inspirals with upcoming space-borne detectors will allow for unprecedented tests of general relativity in the strong-fi…
Pseudospectrum of Reissner-Nordström black holes: quasinormal mode instability and universality
Kyriakos Destounis, Rodrigo Panosso Macedo, Emanuele Berti +2
Black hole spectroscopy is a powerful tool to probe the Kerr nature of astrophysical compact objects and their environment. The observation of multiple ringdown modes in gravitatio…
Gravitational-wave glitches in chaotic extreme-mass-ratio inspirals
Kyriakos Destounis, Arthur G. Suvorov, Kostas D. Kokkotas
The Kerr geometry admits the Carter symmetry, which ensures that the geodesic equations are integrable. It is shown that gravitational waveforms associated with extreme-mass-ratio…
Echoes of Compact Objects in Scalar-Tensor Theories of Gravity
Christoforos Vlachos, Eleftherios Papantonopoulos, Kyriakos Destounis
Scalar-tensor theory predicts solutions to the gravitational field equations which describe compact objects in the presence of a non-minimally coupled scalar field to the Einstein…
Testing spacetime symmetry through gravitational waves from extreme-mass-ratio inspirals
Kyriakos Destounis, Arthur G. Suvorov, Kostas D. Kokkotas
One of the primary aims of upcoming space-borne gravitational wave detectors is to measure radiation in the mHz range from extreme-mass-ratio inspirals. Such a detection would plac…
Stability of the Cauchy horizon in accelerating black-hole spacetimes
Kyriakos Destounis, Rodrigo D. B. Fontana, Filipe C. Mena
The extendibility of spacetime and the existence of weak solutions to the Einstein field equations beyond Cauchy horizons, is a crucial ingredient to examine the limits of General…
