This is the second paper in a series where we examine the physics of pair producing gaps in low-luminosity accreting supermassive black hole systems. In this paper, we carry out time-dependent self-consistent fully general relativistic 1D PIC simulations of the gap, including full inverse Compton scattering and photon tracking. Similar to the previous paper, we find a highly time-dependent solution where a macroscopic vacuum gap can open quasi-periodically, producing bursts of $e^\pm$ pairs and high energy radiation. We present the light curve, particle and photon spectra from this process. Using an empirical scaling relation, we rescale the parameters to the inferred values at the base of the jet in M87, and find that the observed TeV flares could potentially be explained by this model under certain parameter assumptions.

黑洞磁层中成对产生间隙的物理学。二、广义相对论

这是我们研究低光度吸积超大质量黑洞系统中对产生间隙的物理学系列的第二篇论文。在本文中，我们对间隙进行了时间相关的自洽完全广义相对论一维 PIC 模拟，包括完全逆康普顿散射和光子跟踪。与之前的论文类似，我们找到了一个高度依赖于时间的解决方案，其中宏观真空间隙可以准周期性地打开，产生 $e^\pm$ 对和高能辐射的爆发。我们展示了这个过程的光变曲线、粒子和光子光谱。使用经验比例关系，我们将参数重新调整为 M87 中喷流底部的推断值，并发现在某些参数假设下，观察到的 TeV 耀斑可能由该模型解释。
