Abstract

The Orbiting Astronomical Satellite for Investigating Stellar Systems (OASIS), a proposed Astrophysics MIDEX-class mission concept, has an innovative 14-meter diameter inflatable primary mirror that will provide the sensitivity to study far-infrared continuum and line emission from galaxies at all redshifts with high spectral resolution heterodyne receivers. OASIS will have the sensitivity to follow the water trail from galaxies to the comets that create oceans. It will bring an understanding of the role of water in galaxy evolution and its part of the oxygen budget, by measuring water emission from local to intermediate redshift galaxies, observations that have not been possible from the ground. Observation of the ground-state HD line will accurately measure gas mass in a wide variety of astrophysical objects. Thanks to its exquisite spatial resolution and sensitivity, OASIS will, during its one-year baseline mission, detect water in galaxies with unprecedented statistical significance. This paper reviews the extragalactic science achievable and planned with OASIS.

星系外科学与轨道天文卫星调查恒星系统(OASIS)天文台。

用于研究恒星系统的轨道天文卫星(OASIS)是一个被提议的天体物理学midex级任务概念，具有一个创新的14米直径的充气主镜，它将提供灵敏度，研究远红外连续体和来自星系的所有红移的线发射，使用高光谱分辨率外差接收器。OASIS将具有跟踪从星系到形成海洋的彗星的水轨迹的灵敏度。通过测量从局部到中间红移星系的水发射，它将使人们了解水在星系演化中的作用及其在氧气预算中的作用，这在地面上是不可能实现的。对基态HD线的观测将精确测量各种天体的气体质量。由于其精致的空间分辨率和灵敏度，在为期一年的基线任务中，OASIS将以前所未有的统计意义探测星系中的水。本文综述了利用OASIS可以实现和规划的河外科学。

期刊介绍： Space Science Reviews (SSRv) stands as an international journal dedicated to scientific space research, offering a contemporary synthesis across various branches of space exploration. Emphasizing scientific outcomes and instruments, SSRv spans astrophysics, physics of planetary systems, solar physics, and the physics of magnetospheres & interplanetary matter. Beyond Topical Collections and invited Review Articles, Space Science Reviews welcomes unsolicited Review Articles and Special Communications. The latter encompass papers related to a prior topical volume/collection, report-type papers, or timely contributions addressing a robust combination of space science and technology. These papers succinctly summarize both the science and technology aspects of instruments or missions in a single publication.
