论文摘要
我们研究了基于全息原理的宇宙学模型，该模型允许黑物质与黑质红外临界值之间的相互作用。我们通过使用状态的暗能量方程（de eos）的红移参数化（de eos）采用了不可知的观点。遵循这种方法，我们获得了哈勃参数的分析表达，并使用当前万神殿的超新星，宇宙天文钟和星系聚类数据集用DE EOS的四个不同参数进行测试。我们的分析表明，与以前的作品相比，使用了这种不可知论的宇宙扩张，对此不可知论提案进行了考虑的参数化允许加速加速的宇宙扩张，而这些作品的结果是采用了特定形式的互动形式但无法解释这种行为。此外，我们发现我们的提案解决了宇宙学中所谓的巧合问题，并朝着这个方向解决了一些哈勃张力的问题。
We study a cosmological model based on the holographic principle that allows an interaction between dark energy and dark matter with a Hubble infrared cutoff. We adopt an agnostic point of view with respect to the form of the interaction between these dark components by using redshift parameterizations of the dark energy equation of state (DE EoS). Following this approach, we obtain an analytical expression of the Hubble parameter and we test it with four different parameterizations of the DE EoS using currently Pantheon supernovae, Cosmic Chronometers and Galaxy Clustering data sets. Our analyses show that the considered parameterizations on this agnostic proposal allow a late accelerated cosmic expansion in comparison to the results from previous works where specific forms of the interaction are employed but fail to explain this behaviour. Furthermore, we find that our proposal solves the so-called coincidence problem in Cosmology and in this direction shed some light on the problem of the Hubble tension.
