摘要
我们预测了 CORE 在增进我们对宇宙暴胀理解方面的科学能力。CORE 是为响应 ESA 第五次中型任务机会征集而提出的一颗 CMB 空间卫星。CORE 卫星将在跨越 60-600 GHz 范围的 19 个频率通道中绘制温度和偏振的 CMB 各向异性。CORE 在 200 GHz 下将具有 Karcmin 的总噪声灵敏度和 5' 的角分辨率。我们通过对多种仪器配置进行预测，探讨了望远镜尺寸和噪声灵敏度对暴胀科学回报的影响。本研究假设较低和较高频率通道足以去除前景污染，并对组件分离和系统效应的相关研究形成补充，这些研究将在“利用 CORE 探索宇宙起源”系列的其他论文中报告。我们预测了以下能力：确定关键暴胀参数；将张量标量比(tensor-to-scalar ratio)的探测下限降至 量级；绘制单场慢滚暴胀模型的图景；约束再加热时期，从而将暴胀与标准辐射-物质主导的大爆炸时代相联系；重构原初功率谱；将等曲率扰动的贡献约束至 量级；将宇宙弦张力的约束改善至低于假定 GUT 尺度的水平；并将原初非高斯性的当前测量改善至 的水平。在所探索的所有模型中，仅 CORE 本身就将显著改善当前对暴胀物理的约束。其能力将通过与互补的未来宇宙学观测相结合而得到进一步提升。
