摘要
ORIGIN 是响应欧空局 M3 任务征集的一项提案，旨在研究自宇宙黎明时期以来的金属创生。利用软 X 射线波段的高光谱分辨率，ORIGIN 将能够识别从碳（C）到镍（Ni）的所有丰度元素在红移 z=10 及更远时期的物理条件。该任务将回答如下问题：第一批金属是何时产生的？宇宙金属含量如何演化？宇宙中大多数金属存在于何处？金属在结构形成与演化中扮演什么角色？为了触及早期宇宙，ORIGIN 将利用伽马射线暴（GRB）来研究其宿主星系中的局部环境。这要求卫星具备在不到一分钟内转向 GRB 位置的能力。通过研究星系团的化学组成和特性，我们可以将探测范围扩展到更低红移（z ~ 0.2）。为此任务，我们需要一台具有大视场的高分辨率光谱成像仪器。利用同一台仪器，我们还可以研究迄今为止仅被部分探测到的温热-热星系际介质（WHIM）中的重子。WHIM 中密度较低的部分将利用 GRB 光谱中的低红移吸收线进行研究。
