Quasinormal modes of -forms in spherical black holes
arXiv:1901.07723 · doi:10.1103/PhysRevD.99.044054
Abstract
We study the quasinormal modes of -form fields in spherical black holes in -dimensions. Using the spherical symmetry of the black holes and gauge symmetry, we show the -form field can be expressed in terms of the coexact -form and the coexact -form on the sphere . These variables allow us to find the master equations. By utilizing the S-deformation method, we explicitly show the stability of -form fields in the spherical black hole spacetime. Moreover, using the WKB approximation, we calculate the quasinormal modes of the -form fields in -dimensions.
