修改引力中旋转黑洞的新方法与代码

A new approach and code for spinning black holes in modified gravity

Pedro G. S. Fernandes, David J. Mulryne

AI总结:

本文提出一种基于Julia的谱方法代码,用于快速高精度求解修改引力中的旋转黑洞解,并在广义相对论与爱因斯坦-标量-高斯-博内引力中验证其准确性和效率。

摘要:

我们讨论并实现了一种谱方法,用于计算修改引力理论中稳态轴对称黑洞解及其性质。所得到的代码使用Julia语言编写,具有透明性且易于适应新场景。我们在广义相对论和爱因斯坦-标量-高斯-博内引力上测试了该代码。它准确且快速,在这些理论中于数秒内收敛到旋转解,且在大多数情况下误差极小($\sim \mathcal{O}\left(10^{-13}\right)$)。

英文摘要:

We discuss and implement a spectral method approach to computing stationary and axisymmetric black hole solutions and their properties in modified theories of gravity. The resulting code is written in the Julia language and is transparent and easily adapted to new settings. We test the code on both general relativity and on Einstein-Scalar-Gauss-Bonnet gravity. It is accurate and fast, converging on a spinning solution in these theories with tiny errors ($\sim \mathcal{O}\left(10^{-13}\right)$ in most cases) in a matter of seconds.
