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,…
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…
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…
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…
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 Ad…
