Vanishing Love Numbers of Kerr-Newman Black Holes
Sumanta Chakraborty, Takuya Katagiri, Paolo Pani +1
Tidal Love numbers characterize the conservative response of compact objects to external perturbations and provide a powerful probe of their nature. While the static Love numbers o…
Astrophysically Realistic Secondary Spins Trigger Chaos in Schwarzschild Spacetime and Discernible Gravitational Wave Signatures
Dan-Dan Yuan, Jia-Geng Jiao, Yu-Qi Lei +4
Chaos in extreme-mass-ratio inspirals is often thought to require unrealistically large secondary spins, making its astrophysical relevance uncertain. However, we find that chaos p…
Nonlinear tails of massive scalar fields around a black hole
Caiying Shao, Zhen-Tao He, Jiageng Jiao +5
Nonlinear effects play a fundamental role in the late-time ringdown of black holes, with direct implications for gravitational-wave observations. For massive fields, these dynamics…
Reconstruction of Black Hole Ringdown Signals with Data Gaps using a Deep-Learning Framework
Jing-Qi Lai, Jia-Geng Jiao, Cai-Ying Shao +2
We introduce DenoiseGapFiller (DGF), a deep-learning framework specifically designed to reconstruct gravitational-wave ringdown signals corrupted by data gaps and instrumental nois…
Numerical computation of electromagnetically sourced nonlinear tails
Zhen-Tao He, Jia Du, Jiageng Jiao +4
Amazingly, recent studies indicate that nonlinear effects are of great significance for modelling black hole ringdown. Transient electromagnetic events in the astrophysical environ…
The effects of data gaps on ringdown signals with space-based joint observation
Junxi Shi, Jiageng Jiao, Jingqi Lai +3
In space-based gravitational wave observatories such as Taiji, LISA, and TianQin, data gaps are inevitable due to mission design, implementation, and the long duration of observati…
