Perturbation theory of spherically symmetric self-similar black holes
The theory of perturbations of spherically symmetric self-similar black holes is presented, in the Newman-Penrose formalism. It is shown that the wave equations for gravitational, electromagnetic, and scalar waves are separable, though not decoupled. A generalization of the Teukolsky equation is given. Monopole and dipole modes are treated. The Newman-Penrose wave equations governing polar and ...
متن کاملLow frequency quasi-normal modes of AdS black holes
We calculate analytically low frequency quasi-normal modes of gravitational perturbations of AdS Schwarzschild black holes in d dimensions. We arrive at analytic expressions which are in agreement with their counterparts from linearized hydrodynamics in Sd−2×R, in accordance with the AdS/CFT correspondence. Our results are also in good agreement with results of numerical calculations. Research ...
متن کاملAsymptotics of Quasi-normal Modes for Multi-horizon Black Holes
Abstract: The issue concerning rigorous methods recently developed in deriving the asymptotics of quasi-normal modes is revisited and applied to a generic non rotating multi-horizon black holes solution. Some examples are illustrated and the single horizon cases are also considered. As a result, the asymptotics for large angular momentum parameter is shown to depend on the difference between th...
متن کاملQuasi-Normal Modes of Stars and Black Holes
Perturbations of stars and black holes have been one of the main topics of relativistic astrophysics for the last few decades. They are of particular importance today, because of their relevance to gravitational wave astronomy. In this review we present the theory of quasi-normal modes of compact objects from both the mathematical and astrophysical points of view. The discussion includes pertur...
متن کاملGravitational instability of static spherically symmetric Einstein - Gauss - Bonnet black holes in five and six dimensions
Five and six dimensional static, spherically symmetric, asymptotically Euclidean black holes, are unstable under gravitational perturbations if their mass is lower than a critical value set by the string tension. The instability is due to the GaussBonnet correction to Einstein’s equations, and was found in a previous work on linear stability of Einstein-Gauss-Bonnet black holes with constant cu...
