标量诱导引力波综述

Scalar induced gravitational waves review

Guillem Domènech

摘要:

本文综述了由原初涨落引起的引力波的研究现状,即诱导引力波。我们提出了直观的物理背后诱导引力波,我们重新审视和统一的一般分析公式。然后,我们提出了一个紧凑的形式,准备应用的一般公式。这篇评论强调了一种开放的可能性,即原始宇宙经历了与通常假设的辐射主导宇宙学不同的膨胀历史。我们希望任何对这个话题感兴趣的人都能意识到当前诱导引力波宇宙学的进展,并熟悉背后的计算。

英文摘要:

We provide a review on the state-of-the-art of gravitational waves induced by primordial fluctuations, so-called induced gravitational waves. We present the intuitive physics behind induced gravitational waves and we revisit and unify the general analytical formulation. We then present general formulas in a compact form, ready to be applied. This review places emphasis on the open possibility that the primordial universe experienced a different expansion history than the often assumed radiation dominated cosmology. We hope that anyone interested in the topic will become aware of current advances in the cosmology of induced gravitational waves, as well as becoming familiar with the calculations behind.
