朝圣者暗能量的宇宙演化

Cosmological Evolution of Pilgrim Dark Energy

M. Sharif, M. Zubair

摘要:

以红外截止为粒子视界、事件视界和宇宙的共形年龄,研究了Pilgrim暗能量模型。我们推导了分数能量密度的演化方程和朝圣者暗能量的状态方程参数。在这些方案中建立了幻影宇宙演化模型,并得到了$ω_\vartheta$和$ω'_\vartheta$的减速参数、状态参数和相空间等宇宙学参数的支持.我们的结论是,参数$μ$的一致值是$μ<0$,与当前Planck和WMAP的$9$结果一致。

英文摘要:

We study pilgrim dark energy model by taking IR cut-offs as particle and event horizons as well as conformal age of the universe. We derive evolution equations for fractional energy density and equation of state parameters for pilgrim dark energy. The phantom cosmic evolution is established in these scenarios which is well supported by the cosmological parameters such as deceleration parameter, statefinder parameters and phase space of $ω_\vartheta$ and $ω'_\vartheta$. We conclude that the consistent value of parameter $μ$ is $μ<0$ in accordance with the current Planck and WMAP$9$ results.
