Analytic Quasinormal Spectrum of Effective de Sitter Space in Generalized Proca Theory

Zainab Malik

Quasinormal modes describe the relaxation of perturbed black holes and relate ringdown observables to the background geometry. In this work we study the problem in a de Sitter sett…

Analytic Expressions for Quasinormal Modes of a Regular Black Hole Sourced by a Dehnen-Type Halo

Zainab Malik

Using an expansion beyond the eikonal regime, we derive relatively compact and accurate analytic expressions for the gravitational quasinormal modes of an asymptotically flat black…

Long-lived quasinormal modes and grey-body factors of supermassive black holes with a dark matter halo

Zainab Malik

We study quasinormal modes and grey-body factors of a massive scalar field in the background of a Schwarzschild black hole surrounded by a spherically symmetric galactic dark matte…

Bonanno-Reuter regular black hole: quasi-resonances, grey-body factors and absorption cross-sections of a massive scalar field

Zainab Malik

We study quasinormal modes of a massive scalar field in the background of the regular, quantum-corrected Bonanno-Reuter black hole, which arises from the renormalization group impr…

Long-Lived Quasinormal Modes of Brane-Localized Reissner-Nordström--de Sitter Black Holes

Zainab Malik

We study the quasinormal modes of a massive scalar field propagating on the Reissner-Nordström--de Sitter (RNdS) black hole black hole background on a 3+1-dimensional brane embedde…

Correspondence between quasinormal modes and grey-body factors for massive fields in Schwarzschild-de Sitter spacetime

Zainab Malik

Recently, a correspondence between quasinormal modes and grey-body factors of black holes has been established. This correspondence is known to be exact in the eikonal regime for a…

Quasinormal modes and grey-body factors of Morris-Thorne wormholes

Zainab Malik

Using the fact that, for a broad class of Morris-Thorne wormholes, the maximum of the effective potential is located at the throat, we derive accurate analytic WKB expressions for…
