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…
Taxonomy of periodic orbits and gravitational waves in a non-rotating Destounis-Suvorov-Kokkotas black hole spacetime
Zhutong Hua, Zhen-Tao He, Jiageng Jiao +2
In this paper, we investigate periodic orbits of test particles around a non-rotating Destounis-Suvorov-Kokkotas black hole and the resulting gravitational waves. Firstly, we exami…
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…
