CMBPol使命概念研究:绘制我们起源的使命
CMBPol Mission Concept Study: A Mission to Map our Origins
摘要:
宇宙早期暴胀阶段的量子力学度规涨落在宇宙微波背景(CMB)的极化中留下特征印记。该信号的幅度取决于发生暴胀时的能量标度。因此,一个专门的卫星任务(CMBPol)的详细观测提供了关于高达$10^{15}$ GeV的能量尺度的信息,比粒子加速器可获得的最高能量大12个数量级,并探测了宇宙历史上最早的时刻。本摘要概述了一系列研究,探索CMBPol在现代宇宙学的不同领域的科学回报,如膨胀物理学,引力透镜和宇宙再电离,以及前景科学和去除。
英文摘要:
Quantum mechanical metric fluctuations during an early inflationary phase of the universe leave a characteristic imprint in the polarization of the cosmic microwave background (CMB). The amplitude of this signal depends on the energy scale at which inflation occurred. Detailed observations by a dedicated satellite mission (CMBPol) therefore provide information about energy scales as high as $10^{15}$ GeV, twelve orders of magnitude greater than the highest energies accessible to particle accelerators, and probe the earliest moments in the history of the universe. This summary provides an overview of a set of studies exploring the scientific payoff of CMBPol in diverse areas of modern cosmology, such as the physics of inflation, gravitational lensing and cosmic reionization, as well as foreground science and removal .
