چکیده
Quasinormal modes of scalar, electromagnetic, and gravitational fields in the extreme Schwarzschild-de Sitter background are known to be expressed analytic form as eigenvalues P\"oschl-Teller wavelike equation. We show that perturbations fermionic (given by Dirac Rarita-Schwinger equations) do not lead effective potential. Nevertheless, using Frobenius method we find quasinormal analytically this case well. write down analytical formula for frequencies near-extreme black holes, which is valid both bosonic fields. further extend analysis charged rotating holes a general various spin near Kerr-Newman-de spacetime.

Quasinormal modes of D-dimensional de Sitter spacetime
We calculate the exact values of the quasinormal frequencies for an electromagnetic field and a gravitational perturbation moving in D-dimensional de Sitter spacetime (D ≥ 4). We also study the quasinormal modes of a real massive scalar field and we compare our results with those of other references.
متن کاملNeutrino Quasinormal Modes of a Kerr-Newman-de Sitter Black Hole
Using the Pöshl-Teller approximation, we evaluate the neutrino quasinormal modes (QNMs) of a Kerr-Newman-de Sitter black hole. The result shows that for a Kerr-Newman-de Sitter black hole, massless neutrino perturbation of large Λ, positive m and small value of n will decay slowly.

متن کاملNormal Modes, Quasi-normal Modes and Super-radiant Modes for Scalar Fields in Kerr anti-de Sitter Spacetime
Normal modes, quasi-normal modes and super-radiant modes are studied to clarify the total dynamics for complex scalar fields in Kerr anti-de Sitter black hole spacetime. Orthonormal relations and quasi-orthonormal relations are obtained for normal modes and quasi-normal modes. Mode expansions are done and the conserved quantities are studied. Any modes are shown to be separated into two groups,...
متن کاملAbsorption and quasinormal modes of classical fields propagating on 3D and 4D de Sitter spacetime
We extensively study the exact solutions of the massless Dirac equation in 3D de Sitter spacetime that we published recently. Using the Newman-Penrose formalism, we find exact solutions of the equations of motion for the massless classical fields of spin s = 12 , 1, 2 and to the massive Dirac equation in 4D de Sitter metric. Employing these solutions, we analyze the absorption by the cosmologic...
متن کاملQuasinormal modes in Schwarzschild–de Sitter spacetime: A simple derivation of the level spacing of the frequencies
It is known that the imaginary parts of the quasinormal mode ~QNM! frequencies for the Schwarzschild black hole are evenly spaced with a spacing that depends only on the surface gravity. On the other hand, for massless minimally coupled scalar fields, there exist no QNMs in the pure de Sitter spacetime. It is not clear what the structure of the QNMs would be for the Schwarzschild–de Sitter ~SDS...
