宇宙的起源一直是国际关注的热点课题。2013年欧洲的Planck组发布了其对宇宙微波背景辐射的观测结果，证实了暴涨理论的预言。不过Planck的观测也带来了宇宙微波背景温度涨落的大角尺度反常等相关问题。我们认为这些问题与暴涨之前的宇宙演化有关，是暴涨之前极早期宇宙物理一个暗示，因此对其深入地研究将有助于揭示超出暴涨模型的新物理。本项目中申请者将紧密围绕Planck最新的观测数据，致力于解决Planck观测到的反常所带来的理论问题，主要集中于极早期宇宙的唯象模型构造、数值模拟和拟合观测数据等，并探讨其与粒子物理、超弦理论等高能物理理论的联系。

The origin of universe has been still a significant issue. In 2013，Planck collaboration introduced their results on CMB, which is highly consistent with inflation theory. However, it also brang the issues on the CMB anomalies. We think that the solution to these issues is relevant with the evolution before inflation, which might be a hint of pre-inflationary physics, thus the study on the relevant issues will help to uncover the profound physics beyond inflation. In this project. combining the Planck new data, we will solve the issues inspired by Planck observation, mainly concentrate on the building of the phenomenological models of very early universe, numerical simulations, and data fitting, and explore the relation between these issues and the particle physics and the string theory.
