Ricci尺度下的全息暗能量

Holographic dark energy at the Ricci scale

Iván Durán, Diego Pavón

摘要:

我们考虑一个全息宇宙学模型,其中红外截止是固定的里奇长度和暗物质和暗能量不单独发展,但相互作用的非引力相互作用。这实质上简化了宇宙符合问题,因为在整个膨胀过程中,两个分量之间的比率保持有限。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。该模型与观察结果一致。

英文摘要:

We consider a holographic cosmological model in which the infrared cutoff is fixed by the Ricci's length and dark matter and dark energy do not evolve separately but interact non-gravitationally with one another. This substantially alleviates the cosmic coincidence problem as the ratio between both components remains finite throughout the expansion. 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. The model shows consistency with observation.
