摘要
SPHEREx（宇宙历史、再电离时期与冰层探测光谱光度计）( http://spherex.caltech.edu ) 是一颗拟议的全天光谱巡天卫星，旨在实现 NASA 天体物理学部的全部三个科学目标：探究我们宇宙的起源与命运；探索其他恒星周围的行星是否可能孕育生命；以及探索星系的起源与演化。SPHEREx 将系统性地扫描一系列线性可变滤波器以覆盖整个天空。SPHEREx 数据集将包含针对全天每 6.2 角秒像素的 R=40 光谱（对应 4.1m）和 R=150 光谱（对应 4.8m）。在本文中，我们详述了 SPHEREx 所能支持的河外及宇宙学研究，并提出了详细的系统效应评估。我们还概述了冰层与星系演化调查。
