High frequency sources of gravitational waves
Kostas D. Kokkotas
Sources of high frequency gravitational waves are reviewed. Gravitational collapse, rotational instabilities and oscillations of the remnant compact objects are potentially importa…
Stability of five-dimensional rotating black holes projected on the brane
Emanuele Berti, Kostas D. Kokkotas, Eleftherios Papantonopoulos
We study the stability of five-dimensional Myers-Perry black holes with a single angular momentum under linear perturbations, and we compute the quasinormal modes (QNM's) of the bl…
Radiative fields in spacetimes with Minkowski and de Sitter asymptotics
J. Bicak, P. Krtous
The classical Bondi-Penrose approach to the gravitational radiation theory in asymptotically flat spacetimes is recalled and recent advances in the proofs of the existence of such…
Asymptotic quasinormal modes of Reissner-Nordström and Kerr black holes
Emanuele Berti, Kostas D. Kokkotas
According to a recent proposal, the so-called Barbero-Immirzi parameter of Loop Quantum Gravity can be fixed, using Bohr's correspondence principle, from a knowledge of highly-damp…
Quasinormal modes of Reissner-Nordström-anti-de Sitter black holes: scalar, electromagnetic and gravitational perturbations
E. Berti, K. D. Kokkotas
We study scalar, electromagnetic and gravitational perturbations of a Reissner-Nordström-anti-de Sitter (RN-AdS) spacetime, and compute its quasinormal modes (QNM's). We confirm an…
