结构形成的准瞬时暗能量预测

Quinstant Dark Energy Predictions for Structure Formation

Yoelsy Leyva Nodal, Rolando Cardenas, V. F. Cardone

摘要:

我们探讨了一类暗能量模型的预测,quinstant暗能量,在宇宙中的结构形成,无论是在线性和非线性制度。准瞬间暗能量被认为是由精粹和负的宇宙学常数形成的。我们的结论是,这些模型给出了很好的预测结构形成的线性制度,但未能做到这一点,在非线性的红移大于1。

英文摘要:

We explore the predictions of a class of dark energy models, quinstant dark energy, concerning the structure formation in the Universe, both in the linear and non-linear regimes. Quinstant dark energy is considered to be formed by quintessence and a negative cosmological constant. We conclude that these models give good predictions for structure formation in the linear regime, but fail to do so in the non-linear one, for redshifts larger than one.
