Ricci尺度下全息暗能量相互作用模型

A model of interacting holographic dark energy at the Ricci's scale

Ivan Duran, Diego Pavon

摘要:

我们研究了一个全息宇宙学模型,其中红外截止是由里奇长度和暗物质和暗能量不演化自己,但相互作用的非引力。这极大地解释了宇宙巧合问题,因为两个分量之间的比率在任何时候都不会消失。我们约束模型的观测数据从超新星,宇宙背景辐射,重子声学振荡,气体质量分数的星系团,哈勃函数的历史,和增长函数。

英文摘要:

We study a holographic cosmological model in which the infrared cutoff is set by the Ricci's length and dark matter and dark energy do not evolve on their own but interact non-gravitationally with each other. This greatly alleviates the cosmic coincidence problem because the ratio between both components does not vanish at any time. We constrain the model with observational data from supernovae, cosmic background radiation, baryon acoustic oscillations, gas mass fraction in galaxy clusters, the history of the Hubble function, and the growth function.
