长期以来，多个观测探测器的组合一直被认为是限制宇宙学参数，特别是暗能量的一种强有力的技术。暗能量调查已经测量了207条光谱确认的Ia型超新星光曲线、重子声振荡特征、弱引力透镜和星系团。在这里，我们给出了这些探测器的综合结果，得出了对宇宙中暗能量及其能量密度的状态方程w的约束。与其他实验无关，例如那些测量宇宙微波背景的实验，这一单一光度测量的探测器排除了宇宙没有暗能量的可能性，发现w=-0.80_{-0.11}^{+0.09}。几何结构与空间平坦的宇宙是一致的，并且我们得到了Ω_{b}=0.069_{-0.012}^{+0.009}的重子密度的约束，它与早期宇宙的测量无关。这些结果展示了大型多探测器光度测量的潜在力量，并为未来十年我们在暗能量和宇宙学性质的限制方面取得数量级进展铺平了道路。
The combination of multiple observational probes has long been advocated as a powerful technique to constrain cosmological parameters, in particular dark energy. The Dark Energy Survey has measured 207 spectroscopically confirmed type Ia supernova light curves, the baryon acoustic oscillation feature, weak gravitational lensing, and galaxy clustering. Here we present combined results from these probes, deriving constraints on the equation of state, w, of dark energy and its energy density in the Universe. Independently of other experiments, such as those that measure the cosmic microwave background, the probes from this single photometric survey rule out a Universe with no dark energy, finding w=-0.80_{-0.11}^{+0.09}. The geometry is shown to be consistent with a spatially flat Universe, and we obtain a constraint on the baryon density of Ω_{b}=0.069_{-0.012}^{+0.009} that is independent of early Universe measurements. These results demonstrate the potential power of large multiprobe photometric surveys and pave the way for order of magnitude advances in our constraints on properties of dark energy and cosmology over the next decade.
