Quasinormal mode/grey-body factor correspondence for Kerr black holes
Zun-Xian Huang, Peng-Cheng Li
We revisit the quasinormal-mode/greybody factor correspondence for Kerr black holes in the eikonal limit and develop a systematic WKB-based formulation by recasting the radial Teuk…

Constraint on massive vector field with extreme-mass-ratio inspirals around a slowly rotating black hole
Tieguang Zi, Peng-Cheng Li, Bao-Min Gu +1
We study the influence of a massive vector (Proca) field on the energy fluxes from extreme-mass-ratio inspirals (EMRIs) around a slowly rotating Kerr black hole. The secondary comp…

Detection of a Higher Harmonic Quasi-normal Mode in the Ringdown Signal of GW231123
Hai-Tian Wang, Shao-Peng Tang, Peng-Cheng Li +1
The ringdown phase of a gravitational wave signal from a binary black hole merger offers a unique laboratory for testing general relativity in the strong-field regime and probing t…
