暗能量现象学
Dark Energy Phenomenology
摘要：
我们用一阶微扰理论讨论了暗能量的唯象，证明了除非发现了暗物质，否则暗能量不能被完全约束，并证明了在宇宙学探测中，有两个函数可以约束暗扇区的观测性质.我们认为，测量这两个功能应该是观测宇宙学在未来几十年的一个重要目标。
英文摘要：
We discuss the phenomenology of the dark energy in first order perturbation theory, demonstrating that the dark energy cannot be fully constrained unless the dark matter is found, and that there are two functions that characterise the observational properties of the dark sector for cosmological probes. We argue that measuring these two functions should be an important goal for observational cosmology in the next decades.
