Can Oscillatory and Persistent Nonlinearities Be Bridged in Black Hole Ringdown?

Caiying Shao, Hongbao Zhang, Jiageng Jiao, Jing-Qi Lai, Jun-Xi Shi, Yu Tian, Zhen-Tao He

Quadratic quasinormal modes and the Christodoulou memory effect in black hole ringdown are linked by coefficients set by the remnant black hole parameters.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

We show that they are related through bridge coefficients which depend primarily on remnant black hole parameters during ringdown.

C2weakest assumption

The assumption that the bridge coefficients are determined solely by remnant black hole parameters with no significant dependence on initial perturbation details or higher-order nonlinear terms.

C3one line summary

Quadratic quasinormal modes and Christodoulou memory effect are related through bridge coefficients depending primarily on remnant black hole parameters.
