摘要:

小尺度上的原初曲率扰动的性质还不清楚,而大尺度上的原初曲率扰动的性质已经通过对宇宙微波背景各向异性和大尺度结构的观测得到了很好的探索。本文提出了一种通过二元太初黑洞的合并率来重建小尺度上太初曲率扰动的方法,这种合并率可以由小尺度上的太初曲率大扰动来形成.

英文摘要:

The properties of primordial curvature perturbations on small scales are still unknown while those on large scales have been well probed by the observations of the cosmic microwave background anisotropies and the large scale structure. In this paper, we propose the reconstruction method of primordial curvature perturbations on small scales through the merger rate of binary primordial black holes, which could form from large primordial curvature perturbation on small scales.
