Towards constraining of the Horava-Lifshitz gravities
R. A. Konoplya
Recently a renormalizable model of gravity has been proposed, which might be a UV completion of General Relativity (GR) or its infra-red modification, probably with a strongly coup…
Gravitational instability of simply rotating AdS black holes in higher dimensions
Hideo Kodama, R. A. Konoplya, A. Zhidenko
We study the stability of AdS black hole holes rotating in a single two plane for tensor-type gravitational perturbations in space-time dimensions. First, by an analytic me…
Stability of higher dimensional Reissner-Nordstrom-anti-de Sitter black holes
R. A. Konoplya, A. Zhidenko
We investigate stability of the D-dimensional Reissner-Nordstrom-anti-de-Sitter metrics as solutions of the Einstein-Maxwell equations. We have shown that asymptotically anti-de Si…
Instability of higher dimensional charged black holes in the de-Sitter world
R. A. Konoplya, A. Zhidenko
We have shown that higher dimensional Reissner-Nordström-de Sitter black holes are gravitationally unstable for large values of the electric charge and cosmological constant in $D…
Looking at the Gregory-Laflamme instability through quasi-normal modes
R. A. Konoplya, Keiju Murata, Jiro Soda +1
We study evolution of gravitational perturbations of black strings. It is well known that for all wavenumber less than some threshold value, the black string is unstable against sc…
Evolution of perturbations of squashed Kaluza-Klein black holes: escape from instability
Hideki Ishihara, Masashi Kimura, Roman A. Konoplya +3
The squashed Kaluza-Klien (KK) black holes differ from the Schwarzschild black holes with asymptotic flatness or the black strings even at energies for which the KK modes are not e…
