宇宙的FLRW相互作用暗能量模型
An FLRW interacting dark energy model of the Universe
摘要：
在本文中，我们提出了一个FLRW宇宙包含双流体（重子和暗能量）与减速参数（DP）有一个过渡，从过去的减速到现在的加速宇宙。在这个模型中，暗能量（DE）与尘埃相互作用产生了一个新的密度定律。根据我们的模型，我们的宇宙在过去经历了一个精华阶段之后，现在处于一个幻影阶段。从各个方面描述了双流体方案的物理重要性。该模型满足当前的观测约束，如最近的普朗克结果。与宇宙历史有关的各种宇宙学参数已经被研究过了。
英文摘要：
In this paper, we have presented an FLRW universe containing two-fluids (baryonic and dark energy) with a deceleration parameter (DP) having a transition from past decelerating to the present accelerating universe. In this model, dark energy (DE) interacts with dust to produce a new law for the density. As per our model, our universe is at present in a phantom phase after passing through a quintessence phase in the past. The physical importance of the two-fluid scenario is described in various aspects. The model is shown to satisfy current observational constraints such as recent Planck results. Various cosmological parameters relating to the history of the universe have been investigated.
