论文摘要
宇宙中午（红移1 <z <3）的星系的演变经过了一个尘埃刺的相，在尘埃式的阶段，大多数恒星在银河系核中形成，而银河核中的黑洞开始发光，在光学和紫外线上看不到，但需要在中间框架中间框架中间框架中间框架中的中部框架，以要开启启动。在这些频率下，尘埃灭绝是最小的，并且发生了多种原子和分子跃迁，并追踪大多数天体物理结构域。 Spica的未来IR太空望远镜任务目前正在评估第五尺寸的ESA Cosmic Vision任务，并以2.5 m的镜子冷却至t <8k的2.5 m镜子将执行此类观察结果。 Spica将首次提供恒星形成的隐藏侧和在所有环境中的黑洞积聚的3维光谱视图，从空隙到群集核心的90％以上的宇宙时间。在这里，我们概述了Spica在星系进化研究中将要做什么。
The evolution of galaxies at Cosmic Noon (redshift 1<z<3) passed through a dust-obscured phase, during which most stars formed and black holes in galactic nuclei started to shine, which cannot be seen in the optical and UV, but it needs rest frame mid-to-far IR spectroscopy to be unveiled. At these frequencies, dust extinction is minimal and a variety of atomic and molecular transitions, tracing most astrophysical domains, occur. The future IR space telescope mission, SPICA, currently under evaluation for the 5th Medium Size ESA Cosmic Vision Mission, fully redesigned with its 2.5 m mirror cooled down to T < 8K will perform such observations. SPICA will provide for the first time a 3-dimensional spectroscopic view of the hidden side of star formation and black hole accretion in all environments, from voids to cluster cores over 90% of cosmic time. Here we outline what SPICA will do in galaxy evolution studies.
