暗能量的崛起

The Rise of Dark Energy

Eric V. Linder

摘要:

虽然暗能量只是在$z\approx0.7$之后才主导宇宙动力学,但它的能量密度仍然是$z\approx2.5$之外的$\gtrsim5\%$。我们计算模型独立的限制,其分数从未来的星系调查,发现暗能量的上升,可以检测到在$3σ$几乎出$z\approx2.5$。

英文摘要:

While dark energy has dominated cosmic dynamics only since $z\approx0.7$, its energy density was still $\gtrsim5\%$ of the total out to $z\approx2.5$. We calculate model independent constraints on its fraction from future galaxy surveys, finding that the rise of dark energy could be detected at $3σ$ nearly out to $z\approx2.5$.
