Extended parameterized spin expansion formalism for ringdown analysis with GW250114
Jia-Ning Chen, Liang-Bi Wu, Zong-Kuan Guo
Parameterized descriptions of black-hole quasinormal-mode spectra are essential for testing gravity with ringdown observations. We extend the Parameterized Spin Expansion Coefficie…

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…

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…
