摘要

我们概述了美国宇航局（NASA）探测级远红外（IR）任务概念中的银河系（MW）和附近星系科学案例。与以前的远红外任务相比，SALTUS 的 14 米主反射镜温度较低（<40 K），因此在空间分辨率和光谱灵敏度方面都有很大提高。SALTUS 的主要中波和邻近星系科学目标侧重于了解恒星形成在本宇宙反馈中的作用。除了这个科学案例之外，SALTUS 还将在 2030 年代为银河系和河外星系社区打开一扇新窗口，从根本上回答新问题，并将成为詹姆斯-韦伯太空望远镜近红外和中红外能力的远红外类似物。我们总结了中波和近邻星系的科学案例，以及在保证时间和客座（开放）时间的名义观测计划。

Milky Way and nearby galaxy science with the SALTUS space observatory

We present an overview of the Milky Way (MW) and nearby galaxy science case for the Single Aperture Large Telescope for Universe Studies (SALTUS) far-infrared (IR) NASA probe-class mission concept. SALTUS offers enormous gains in spatial resolution and spectral sensitivity over previous far-IR missions due to its cold (<40 K) 14-m primary mirror. Key MW and nearby galaxy science goals for SALTUS focus on understanding the role of star formation in feedback in the local universe. In addition to this science case, SALTUS would open a new window to galactic and extragalactic communities in the 2030s, enabling fundamentally new questions to be answered, and would be a far-IR analog to the near- and mid-IR capabilities of the James Webb Space Telescope. We summarize the MW and nearby galaxy science case and plans for notional observing programs in both guaranteed and guest (open) times.
