论文摘要
限制通货膨胀时期是现代宇宙学的目的之一。为了完全利用当前和未来的小规模观察，有必要设计工具将它们直接与早期宇宙动态联系起来。我们在这里提出了一种新型的逆向工程方法，能够将基本的后期可观察物与稳定的通货膨胀动态连接起来，并最终将其与充气电位联系起来。采用此过程，我们能够描述哪些条件可以在小尺度上的曲率扰动功率范围内引起升高的平稳谱，而曲率扰动的功率谱则不会受到CMB观测值的约束。在这种新的现象学驱动的方法中，我们发现通货膨胀可以在曲率扰动范围内产生高原，这些曲线扰动可能会连接三种基本可观察物：黑物质的主要组成部分以小星座质量/原子/原子 - 原子/原子 - 原子量大小为原始黑洞的形式；随机重力波和恒星原始黑洞合并的亚尺寸比例的可检测信号。
Constraining the inflationary epoch is one of the aims of modern cosmology. In order to fully exploit current and future small-scale observations, it is necessary to devise tools to directly relate them to the early universes dynamics. We present here a novel reverse engineer approach able to connect fundamental late-time observables to consistent inflationary dynamics and, eventually, to the inflaton potential. Employing this procedure, we are able to describe which conditions can give rise to a raised plateau in the power spectrum of curvature perturbations at small scales, which are not constrained by CMB observations. Within this new phenomenologically-driven approach, we find that inflation can generate a raised plateau in the spectrum of curvature perturbations that potentially connects three fundamental observables: a dominant component of the dark matter in the form of asteroid-mass/atomic-size primordial black holes; detectable signals in stochastic gravitational waves and a subdominant fraction of stellar-mass primordial black holes mergers.
