The fastest x-ray variability arises from close to the event horizon of the black hole, and is known to be strongly energy dependent. Recent progress in understanding this focuses on density fluctuations propagating down through a radially stratified accretion flow. The project will build the first physically based numerical models of this, and fit them to real data, to derive constraints on the accretion flow close to the black hole.

最快的x射线变异性出现在接近黑洞视界的地方，并且已知强烈依赖于能量。最近在理解这方面的进展集中在通过径向分层吸积流向下传播的密度波动上。该项目将建立第一个基于物理的数值模型，并将其与实际数据相匹配，以得出黑洞附近吸积流的约束条件。
