Perturbative Approach to the Quasinormal Modes of Dirty Black Holes
نویسندگان
چکیده
Using a recently developed perturbation theory for uasinormal modes (QNM’s), we evaluate the shifts in the real and imaginary parts of the QNM frequencies due to a quasi-static perturbation of the black hole spacetime. We show the perturbed QNM spectrum of a black hole can have interesting features using a simple model based on the scalar wave equation. PACS numbers: 04.30.Db Typeset using REVTEX 1

Perturbative Calculation of Quasinormal Modes of d–Dimensional Black Holes
We study analytically quasinormal modes in a wide variety of black hole spacetimes, including d–dimensional asymptotically flat spacetimes and non-asymptotically flat spacetimes (particular attention has been paid to the four dimensional case). We extend the analytical calculation to include first-order corrections to analytical expressions for quasinormal mode frequencies by making use of a mo...
متن کاملAbout the Signiicance of Quasinormal Modes of Black Holes
Quasinormal modes have played a prominent role in the discussion of perturbations of black holes, and the question arises whether they are as signiicant as normal modes are for self adjoint systems, such as harmonic oscillators. They can be signiicant in two ways: Individual modes may dominate the time evolution of some perturbation, and a whole set of them could be used to completely describe ...
متن کاملQuasinormal modes for Weyl neutrino field in R-N black holes
We employ WKB approximation up to the third order to determine the low-lying quasinormal modes for Weyl neutrino field in R-N black holes, which are the most relevant to the evolution of the field around a black hole in the intermediate stage. It is showed that the quasinormal mode frequencies for Weyl neutrino field in R-N black holes are different from those in Schwartzchild black holes ownin...

متن کاملQuasinormal modes of Reissner-Nordström Anti-de Sitter black holes
Complex frequencies associated with quasinormal modes for large ReissnerNordström Anti-de Sitter black holes have been computed. These frequencies have close relation to the black hole charge and do not linearly scale with the black hole temperature as in Schwarzschild Anti-de Sitter case. In terms of AdS/CFT correspondence, we found that the bigger the black hole charge is, the quicker for the...
