We investigate the quasinormal modes (QNMs) of a thick brane model in gravity with . Requiring the energy density to remain positive and the scalar field to…
Quasinormal Ringing of de Sitter Braneworlds
Hai-Long Jia, Wen-Di Guo, Yu-Xiao Liu +1
Compared with the Poincaré braneworld, the de Sitter (dS) braneworld aligns more closely with the present universe characterized by a small but finite cosmological constant. To exp…
Parameterized quasinormal frequencies and Hawking radiation for axial gravitational perturbations of a holonomy-corrected black hole
Sen Yang, Wen-Di Guo, Qin Tan +2
As the fingerprints of black holes, quasinormal modes are closely associated with many properties of black holes. Especially, the ringdown phase of gravitational waveforms from the…
Quasinormal ringing of thick braneworlds with a finite extra dimension
Hai-Long Jia, Wen-Di Guo, Qin Tan +1
In this work, we investigate the quasinormal modes of the Poincaré thick brane with a finite extra dimension. Unlike the case with an infinite extra dimension, the gravitational ef…
