Radial spectra and dynamical signatures of excited boson stars
Chen-Hao Hao, Wen-Di Guo, Qin Tan +1
We compute the lowest radial mode of spherically symmetric boson stars along equilibrium branches with a fixed number of radial nodes, considering both mini boson stars and quartic…
Real Part Emergence in Purely Imaginary Quasinormal Modes in Perturbed de Sitter Braneworlds
Hai-Long Jia, Wen-Di Guo, Yun-Tao Gu +1
For braneworlds with infinite extra dimensions, an analysis of the stability of the characteristic spectrum is essential for understanding their dynamical properties. In this study…
Spectral Butterfly Effect and Resilient Ringdown in Thick Braneworlds
Hai-Long Jia, Wen-Di Guo, Yu-Peng Zhang +1
The quasinormal mode spectrum is a unique fingerprint linking gravitational-wave observations to extra-dimensional geometry. In this Letter, we show that thick braneworlds exhibit…
Quasinormal modes of a charged spherically symmetric black hole in bumblebee gravity
Bo-Rui Li, Jia-Zhou Liu, Wen-Di Guo +1
Recently, exact charged spherically symmetric black hole solutions within the framework of bumblebee gravity have been obtained, where the Lorentz symmetry is spontaneously broken…
Quasinormal modes of an electrically charged Kalb-Ramond black hole
Yun-Tao Gu, Wen-Di Guo, Yu-Xiao Liu
Lorentz violation serves as a significant feature in many modified theories of gravity. In particular, spontaneous Lorentz violation induced by the Kalb-Ramond field has attracted…
Charged spherically symmetric and slowly rotating charged black hole solutions in bumblebee gravity
Jia-Zhou Liu, Wen-Di Guo, Shao-Wen Wei +1
In this paper, we present charged spherically symmetric black hole solutions and slowly rotating charged solutions in bumblebee gravity with and without a cosmological constant. Th…
