论文摘要
黑洞已经变成了宇宙实验室，以通过超级不稳定性来搜索超光标度。在本文中，我们详细介绍了超级进化对黑洞阴影的影响，并调查了未来对基线长期干涉法的观察结果进行探索的令人兴奋的可能性。我们在绝热状态下以数值为单位模拟了超级进化，并衍生出对过程进行建模的分析近似。在超级驱动的驱动下，我们进化了黑洞阴影直径，（i）发现它可以改变几美元$ $，因为在事件地平线望远镜的当前分辨率下方，尽管在时间尺度上比现实的观察时间更长； （ii）表明阴影直径可以收缩或生长； （iii）详细探讨了阴影的最终状态如何取决于初始参数和耦合。
Black holes have turned into cosmic laboratories to search for ultra-light scalars by virtue of the superradiant instability. In this paper we present a detailed study of the impact of the superradiant evolution on the black hole shadow and investigate the exciting possibility to explore it with future observations of Very Long Baseline Interferometry. We simulated the superradiant evolution numerically, in the adiabatic regime, and derived analytic approximations modelling the process. Driven by superradiance, we evolve the black hole shadow diameter and (i) find that it can change by a few $μ$as, just below the current resolution of the Event Horizon Telescope, albeit on timescales that are longer than realistic observation times; (ii) show that the shadow diameter can either shrink or grow; and (iii) explore in detail how the shadow's end state is determined by the initial parameters and coupling.
