The quasinormal modes of the rotating quantum corrected black holes
Jia-Ning Chen, Zong-Kuan Guo, Liang-Bi Wu
The quasinormal modes (QNMs) of a rotating quantum corrected black hole (RQCBH) are studied by employing the hyperboloidal framework for the scalar perturbation. This framework is…
Waveform stability for the piecewise step approximation of Regge-Wheeler potential
Liang-Bi Wu, Libo Xie, Yu-Sen Zhou +2
By interpreting the difference between the original Regge-Wheeler potential and its piecewise step approximation as perturbative effects induced by the external environment of the…
Resolving the Planck-DESI tension by nonminimally coupled quintessence
Jia-Qi Wang, Rong-Gen Cai, Zong-Kuan Guo +1
The Planck measurement of the cosmic microwave background (CMB) has established the -cold-dark-matter (CDM) model as the concordant model along with other observations. Howev…
Spectrum instability and greybody factor stability for parabolic approximation of Regge-Wheeler potential
Libo Xie, Liang-Bi Wu, Zong-Kuan Guo
We investigate the stability of QNM spectra and greybody factors in the Schwarzschild black hole by approximating the Regge-Wheeler potential with a piecewise parabolic form and tr…
The pseudospectrum for the Kerr black hole with spin case
Rong-Gen Cai, Li-Ming Cao, Jia-Ning Chen +3
We investigate the pseudospectrum of the Kerr black hole, which indicates the instability of the spectrum of quasinormal modes (QNMs) of the Kerr black hole. Methodologically, we u…
