论文摘要
我们介绍了Cassegrain U波段有效光谱仪（立方体）开发的科学动机，该光谱仪（立方体）现在正在为非常大的望远镜建造。组装的案例跨越了太阳系，银河系和外层天文学的广泛当代主题，在该天文学中，观察结果受到当前地面光谱仪的性能的限制。提出了每种情况的简短背景，并确定了从每种情况下流下的仪器设计的具体技术要求。这些被用作立方体设计的输入，将在300-405nm以上的天文光谱效率上获得十倍的效率，并在r 〜24,000和〜7,000的分辨能力下提供。我们包括绩效估计值，这些估计值证明了立方体观察到的来源的能力，这些资源比目前在地面粉状群波长中可能占有三个幅度的来源，并且我们将其预测的性能放在现有的成分的背景下。
We introduce the scientific motivations for the development of the Cassegrain U-Band Efficient Spectrograph (CUBES) that is now in construction for the Very Large Telescope. The assembled cases span a broad range of contemporary topics across Solar System, Galactic and extragalactic astronomy, where observations are limited by the performance of current ground-based spectrographs shortwards of 400nm. A brief background to each case is presented and specific technical requirements on the instrument design that flow-down from each case are identified. These were used as inputs to the CUBES design, that will provide a factor of ten gain in efficiency for astronomical spectroscopy over 300-405nm, at resolving powers of R~24,000 and ~7,000. We include performance estimates that demonstrate the ability of CUBES to observe sources that are up to three magnitudes fainter than currently possible at ground-ultraviolet wavelengths, and we place its predicted performance in the context of existing facillities.
