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…
Total transmission modes in draining bathtub model with vorticity
Zhe Yu, Liang-Bi Wu
We investigate the total transmission modes (TTMs) in the draining bathtub model (DBM) with vorticity using the Chebyshev-Lobatto pseudospectral method, where the boundary conditio…
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…
Virtual absorption modes of Schwarzschild-de Sitter spacetimes in semi-open systems
Liang-Bi Wu, Yu-Sen Zhou, Zhe Yu +2
We present a study of virtual absorption modes (VAMs) in Schwarzschild-de Sitter (SdS) spacetime under semi-open boundary conditions, where the VAMs correspond to total transmissio…
QNM families: classification and competition
Zhen-Hao Yang, Liang-Bi Wu, Xiao-Mei Kuang +1
The perturbation spectra of black holes beyond standard vacuum black hole solutions within generalrelativity (GR) may exhibit complex structures with long-lived modes. This usually…
