Quasinormal modes of a Proca field in Schwarzschild-AdS spacetime via the isomonodromy method
Julián Barragán Amado, Tiago V. Fernandes, David C. Lopes
We consider Proca field perturbations in a five-dimensional Schwarzschild-anti-de Sitter (Schwarzschild-AdS) black hole geometry. Using the vector spherical harmonic (VSH) me…
The effect of resummation on retarded Green's function and greybody factor in black holes
Julián Barragán Amado, Shankhadeep Chakrabortty, Arpit Maurya
We investigate the retarded Green's function and the greybody factor in asymptotically AdS black holes. Using the connection coefficients of the Heun equation, expressed in terms o…
QNMs of scalar fields on small Reissner-Nordström-AdS black holes
Julián Barragán Amado, Bruno Carneiro da Cunha, Elisabetta Pallante
We study the quasinormal modes (QNMs) of a charged scalar field on a Reissner-Nordström-anti-de Sitter (RN-AdS) black hole in the small radius limit by using the isomonodromi…
