论文摘要
随着JWST的推出以及即将到来的极大望远镜的安装，我们宇宙中的第一个星系最终将被揭示。它们的光将由巨大的恒星主导，恒星在电磁谱的超紫（UV）部分中达到峰值。星形形成是我们宇宙发展的关键驱动力。在年轻的年龄，在1000万年内，高质量恒星都会产生复杂的紫外线排放过程，这些过程知之甚少，但对于解释高红移线排放至关重要。由于这些原因，哈勃太空望远镜（HST）将投入1000轨，以获取年轻恒星的紫外线遗产库作为必不可少的标准（Ullyses）。此概述的目的是概述从恒星形成（100个parsecs）驱动紫外线排放过程的基本物理原理，范围从包含数百种巨大和非常庞大的恒星（VM）的巨大恒星形成络合物（例如30多拉多斯（Tarantula nebula））在相邻的岩质云中（Tarantula nebula），仅在附近的Magellanic Clouds（Tarantula nebula）到近距离的50 kpc），直到频繁的50 kpc）到天然气，到天然气的范围（To）宇宙电源。
With the launch of JWST and the upcoming installation of extremely large telescopes, the first galaxies in our Universe will finally be revealed. Their light will be dominated by massive stars, which peak in in the ultra-violet (UV) part of the electromagnetic spectrum. Star formation is the key driver of the evolution of our Universe. At young ages, within 10 Million years, both high and low mass stars generate complex UV emission processes which are poorly understood yet are vital for interpreting high red-shift line emission. For these reasons, the Hubble Space Telescope (HST) will devote 1000 orbits to obtaining a UV Legacy Library of Young Stars as Essential Standards (ULLYSES). The purpose of this Overview is to outline the basic physical principles driving UV emission processes from local (within 100 parsecs of) star formation, ranging from huge star-forming complexes containing hundreds of massive and very-massive stars (VMS), such as 30 Doradus (the Tarantula Nebula) in the neighbouring Magellanic Clouds (only 50 kpc away), to galaxies near and far, out to the epoch of Cosmic Reionization.
