We present an overview of the high-redshift extragalactic science case for the Single Aperture Large Telescope for Universe Studies (SALTUS) far-infrared (IR) National Aeronautics and Space Administration probe-class mission concept. Enabled by its 14-m primary reflector, SALTUS offers enormous gains in spatial resolution and spectral sensitivity over previous far-IR missions. SALTUS would be a versatile observatory capable of responding to the scientific needs of the extragalactic community in the 2030s and a natural follow-on to the near- and mid-IR capabilities of JWST. The key early-universe science goals for SALTUS focus on understanding the role of galactic feedback processes in regulating galaxy growth across cosmic time and charting the rise of metals and dust from the early universe to the present. We summarize these science cases and the performance metrics most relevant for high-redshift observations.

利用用于宇宙研究的单孔径大型望远镜 (SALTUS) 空间天文台进行高红移河外科学


我们概述了用于宇宙研究的单孔径大型望远镜 (SALTUS) 远红外 (IR) 美国国家航空航天局探测器级任务概念的高红移河外科学案例。凭借其 14 米主反射镜，SALTUS 比以前的远红外任务在空间分辨率和光谱灵敏度方面取得了巨大的进步。 SALTUS 将是一个多功能天文台，能够满足 2030 年代河外界的科学需求，也是 JWST 近红外和中红外能力的自然后续产品。 SALTUS 的关键早期宇宙科学目标侧重于了解星系反馈过程在调节整个宇宙时间的星系生长中的作用，并绘制从早期宇宙到现在的金属和尘埃的崛起图表。我们总结了这些科学案例以及与高红移观测最相关的性能指标。
