摘要:

我们报告了银河系附近的暗能量的检测与精确观测当地的哈勃膨胀流。我们估计了暗能量的局部密度,发现它接近,如果不完全等于,全球暗能量密度。这一结果与首次发现暗能量的视界尺度观测结果是独立的、相容的和互补的。与宇宙学一致性数据一起,我们的结果形成了爱因斯坦反引力作为一种普遍现象的直接观测证据-与牛顿万有引力相同。

英文摘要:

We report the detection of dark energy near the Milky Way made with precision observations of the local Hubble flow of expansion. We estimate the local density of dark energy and find that it is near, if not exactly equal to, the global dark energy density. The result is independent of, compatible with, and complementary to the horizon-scale observations in which dark energy was first discovered. Together with the cosmological concordance data, our result forms direct observational evidence for the Einstein antigravity as a universal phenomenon -- in the same sense as the Newtonian universal gravity.
