Scalar quasinormal modes of Kerr--AdS via accessory parameter expansions
Julián Barragán Amado
We study scalar perturbations of a seven-dimensional Kerr--AdS black hole with three independent rotation parameters. In this geometry, the Klein--Gordon equation separates into on…
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…
Scalar quasi-normal modes of accelerating Kerr-Newman-AdS black holes
Julián Barragán Amado, Bogeun Gwak
We study linear scalar perturbations of slowly accelerating Kerr-Newman-anti-de Sitter black holes using the method of isomonodromic deformations. The conformally coupled Klein-Gor…
Absorption cross section in gravity's rainbow from confluent Heun equation
Kihong Kwon, Julián Barragán Amado, Bogeun Gwak
We investigate the scattering of a massless scalar field by a charged non-rotating black hole in the presence of gravity's rainbow. Using the connection coefficients of the conflue…
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…
Remarks on holographic models of the Kerr-AdS geometry
Julián Barragán Amado, Bruno Carneiro da Cunha, Elisabetta Pallante
We study the low-temperature limit of scalar perturbations of the Kerr-AdS black-hole for generic rotational parameters. We motivate the study by considering real-time hologr…
On the Kerr-AdS/CFT correspondence
Julián Barragán Amado, Bruno Carneiro da Cunha, Elisabetta Pallante
We review the relation between four-dimensional global conformal blocks and field propagation in . Following the standard argument that marginal perturbations should b…
