چکیده
Abstract We study the linear instability of charged massless scalar perturbation in regularized 4D Einstein-Gauss-Bonnet-AdS black holes by exploring their quasinormal modes. find that is triggered superradiance. The becomes more unstable with increasing Gauss-Bonnet coupling constant or hole charge. Decreasing AdS radius, on other hand, will make stable. stable region parameter space ( ? , Q ?) given. Moreover, we for larger modes multipoles are than monopole.

Instability of charged black holes in anti - de Sitter space
A curious dichotomy in the physics of black holes is that they typically are thermodynamically unstable, in that they have negative specific heat; but in a classical treatment, they are stable against small perturbations of the metric (see for example [1, 2] for discussions of Schwarzschild and Kerr black holes in asymptotically flat space). In the past several years, following [3], there has b...
متن کاملNUT-Charged Black Holes in Gauss-Bonnet Gravity
We investigate the existence of Taub-NUT/bolt solutions in Gauss-Bonnet gravity and obtain the general form of these solutions in d dimensions. We find that for all nonextremal NUT solutions of Einstein gravity having no curvature singularity at r = N , there exist NUT solutions in Gauss-Bonnet gravity that contain these solutions in the limit that the Gauss-Bonnet parameter α goes to zero. Fur...
متن کاملGlobal Properties of Charged Dilatonic Gauss-bonnet Black Holes
We study the phase space of the spherically symmetric solutions of Einstein-Maxwell-Gauss-Bonnet system nonminimally coupled to a scalar field and prove the existence of solutions with unusual asymptotics in addition to asymptotically flat ones. We also find new dyonic solutions of dilatonic Einstein-Maxwell theory.
متن کاملEinstein-Gauss-Bonnet black holes in de Sitter spacetime and the quasilocal formalism
We propose to compute the action and global charges of the asymptotically de Sitter solutions in Einstein-Gauss-Bonnet theory by using the counterterms method in conjunction with the quasilocal formalism. The general expression of the counterterms and the boundary stress tensor is presented for spacetimes of dimension d ≤ 7. We apply this tehnique for several different solutions in Einstein-Gau...
متن کاملInstability of higher-dimensional charged black holes in the de sitter world.
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>or=7 space-time dimensions. We have found the shape of the slightly perturbed black hole at the threshold point of instability.
