黑暗区宇宙学

The Dark Sector Cosmology

Elcio Abdalla, Alessandro Marins

摘要:

基础物理学中最重要的问题是描述宇宙的内容。今天,我们知道其中95%是完全未知的。其中三分之二是一篇有趣而重要的评论中描述的神秘的暗能量。我们在这里简要地扩展了该评论中包含的想法,包括更一般的暗区,即暗物质和暗能量,最终组成一个新的物理部门。精确地理解暗区对于我们能够全面理解所有其他宇宙学参数至关重要,因为模型的修改可能导致模型推断参数的潜在偏差,例如哈勃常数和距离指标的测量,如重子声学振荡。我们将讨论几种现代观测方法,它们可以解开对黑暗区的不同可能描述。本文还包括一些理论发展的可能应用,以及在较低频率和引力波的新的观测技术的更彻底的评价。

英文摘要:

The most important problem in fundamental physics is the description of the contents of the Universe. Today, we know that 95% thereof is totally unknown. Two thirds of that amount is the mysterious Dark Energy described in an interesting and important review. We briefly extend here the ideas contained in that review including the more general Dark Sector, that is, Dark Matter and Dark Energy, eventually composing a new physical Sector. Understanding the Dark Sector with precision is paramount for us to be able to understand all the other cosmological parameters comprehensively as modifications of the modelling could lead to potential biases of inferred parameters of the model, such as measurements of the Hubble constant and distance indicators such as the Baryon Acoustic Oscillations. We discuss several modern methods of observation that can disentangle the different possible descriptions of the Dark Sector. The possible application of some theoretical developments are also included in this paper as well as a more thorough evaluation of new observational techniques at lower frequencies and gravitational waves.
