非平坦宇宙中的相互作用年龄暗能量模型

Interacting agegraphic dark energy models in non-flat universe

Ahmad Sheykhi

摘要:

最近有人提出了一种所谓的“年龄暗能量“来解释暗能量主导的宇宙。在这封信中,我们将年龄图暗能量模型推广到存在暗物质和暗能量相互作用的具有空间曲率的宇宙。我们证明了这些模型可以容纳暗能量状态方程的$w_D = -1 $交叉。在平坦宇宙的极限情况下,即$k = 0$,恢复了以往关于平坦宇宙年龄学暗能量的所有结果。

英文摘要:

A so-called "agegraphic dark energy" was recently proposed to explain the dark energy-dominated universe. In this Letter, we generalize the agegraphic dark energy models to the universe with spatial curvature in the presence of interaction between dark matter and dark energy. We show that these models can accommodate $w_D = -1 $ crossing for the equation of state of dark energy. In the limiting case of a flat universe, i.e. $k = 0$, all previous results of agegraphic dark energy in flat universe are restored.
