暗物质和暗能量相互作用的模型已经被提出来解决巧合问题。我们回顾的动机需要引入这样的相互作用，它的背景动力学的影响，以及它如何修改的线性扰动的演变。我们使用最新的观测数据来测试模型，我们发现这种相互作用与当前的天文学和宇宙学数据是兼容的。最后，我们描述了即将到来的数据集，从当前和未来的设施，正在建设或设计，将允许更清楚地了解暗区的物理。
Models where dark matter and dark energy interact with each other have been proposed to solve the coincidence problem. We review the motivations underlying the need to introduce such interaction, its influence on the background dynamics and how it modifies the evolution of linear perturbations. We test models using the most recent observational data and we find that the interaction is compatible with the current astronomical and cosmological data. Finally, we describe the forthcoming data sets from current and future facilities that are being constructed or designed that will allow a clearer understanding of the physics of the dark sector.
