Probing near-zone magnetic fields with extreme mass-ratio inspirals
Jin-Lu Hu, Xin-Dong Du, Peng-Cheng Li +1
We investigate whether weak near-zone magnetic fields can leave observable imprints on extreme-mass-ratio inspiral (EMRI) waveforms. The central massive black hole is modeled by th…
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…
Stable massless scalar polarization of f(R) gravity
Xin-Dong Du, Peng-Cheng Li
Polarization is a prominent feature of gravitational wave observations and can be used to distinguish between different modified gravity theories. Compared to General Relativity, f…
