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…
Can Oscillatory and Persistent Nonlinearities Be Bridged in Black Hole Ringdown?
Jun-Xi Shi, Zhen-Tao He, Jiageng Jiao +4
Quadratic quasinormal modes (QQNMs) and Christodoulou memory effect are key nonlinear phenomena in gravitational wave physics. QQNMs characterize the near zone nonlinear response o…
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…
Internal structure of Hayward black holes
Caiying Shao, Jun-Qi Guo, Yu Tian +1
Regular black holes, free of central singularities, provide an ideal laboratory for probing the geometric structure of spacetime. The global structure of some regular black holes,…
Emergence of critical phenomena from the black hole interior
Caiying Shao, Junqi Guo, Yu Tian +1
The emergence of the singularity inside a spherically symmetric charged black hole, is studied numerically within the Einstein-Maxwell-real scalar model. When the scalar fiel…
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…
Quantum Gravity Corrections to the Scalar Quasi-Normal Modes in Near-Extremal Reissener-Nordström Black Holes
Zheng Jiang, Jun Nian, Caiying Shao +2
We investigate quantum corrections to scalar quasi-normal modes (QNMs) in the near-extremal Reissner-Nordström black hole background with quantum correction in the near-horizon AdS…
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…
