Extended parameterized spin expansion formalism for ringdown analysis with GW250114
Jia-Ning Chen, Liang-Bi Wu, Zong-Kuan Guo
The paper extends the Parameterized Spin Expansion Coefficients (ParSpec) framework to jointly sample a characteristic length scale and a scaling index for black‑hole quasinormal‑m…
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…
The pseudospectrum and transient of Kaluza-Klein black holes in Einstein-Gauss-Bonnet gravity
Jia-Ning Chen, Liang-Bi Wu, Zong-Kuan Guo
The spectrum and dynamical instability, as well as the transient effect of the tensor perturbation for the so-called Maeda-Dadhich black hole, a type of Kaluza-Klein black hole, in…
