Making use of the generalized form of the Ghost dark energy density, which has the functional form ρG = f(H,H2) where H represents the Hubble expanding rate, the present accelerated enlargement behavior of the cosmos is investigated from the Rastall theory perspective. After finding a relation for the Hubble cosmic expansion rate, we consider recent cosmology-independent measurements calculated for the expansion history of the cosmos to fit the model via the χ2-analysis. Moreover, we discuss the cosmographic properties of the model with the help of some cosmological quantities. We show that our model is stable and consistent with the recent astrophysical data. Also, for our model, we investigate cosmological interpretations of thermodynamics.

拉斯托理论中的幽灵暗能量

利用Ghost暗能量密度的广义形式,它具有泛函形式ρG = F(H,H2)在哪里H代表哈勃膨胀率,从拉斯托尔理论的角度研究宇宙目前的加速膨胀行为。在找到哈勃宇宙膨胀率的关系后,我们考虑最近为宇宙膨胀历史计算的与宇宙学无关的测量值,以通过χ2-分析。此外,我们在一些宇宙学量的帮助下讨论了模型的宇宙学特性。我们表明我们的模型是稳定的,并且与最近的天体物理数据一致。此外,对于我们的模型,我们研究了热力学的宇宙学解释。
