ELT-MOS（MOSAIC）：进入建设阶段
The ELT-MOS (MOSAIC): towards the construction phase
摘要：
当与ELT的巨大收集区域相结合时，MOSAIC将成为世界上最有效和最灵活的多目标光谱仪（MOS）设施，具有高度多路复用和多积分现场单元（Multi-IFU）能力。这将是光谱跟踪最微弱的来源，探测再电离时代以及评估宇宙大部分年龄中矮质量函数演变的最快方法。MOSAIC将在生成暗物质（来自MOAO馈入近红外IFU的真实旋转曲线）和z=3.5星系晕中的冷到温热气相（具有可见波长IFU）的清单方面处于世界领先地位。银河考古学和第一个巨大的黑洞是额外的目标，其中马赛克也将是革命性的。MOAO和使用光纤的精确天空减法现在已经在天空上得到了验证，从仪器中删除了所有低技术准备水平（TRL）项目。MOSAIC的迅速实现是可行的，并且确实可以增加ELT的鲁棒性并降低风险，因为它不需要衍射限制自适应光学性能。联合会目前正在研究科学方案和调查战略，并希望在今后两年中欢迎一些新的合作伙伴。
英文摘要：
When combined with the huge collecting area of the ELT, MOSAIC will be the most effective and flexible Multi-Object Spectrograph (MOS) facility in the world, having both a high multiplex and a multi-Integral Field Unit (Multi-IFU) capability. It will be the fastest way to spectroscopically follow-up the faintest sources, probing the reionisation epoch, as well as evaluating the evolution of the dwarf mass function over most of the age of the Universe. MOSAIC will be world-leading in generating an inventory of both the dark matter (from realistic rotation curves with MOAO fed NIR IFUs) and the cool to warm-hot gas phases in z=3.5 galactic haloes (with visible wavelenth IFUs). Galactic archaeology and the first massive black holes are additional targets for which MOSAIC will also be revolutionary. MOAO and accurate sky subtraction with fibres have now been demonstrated on sky, removing all low Technical Readiness Level (TRL) items from the instrument. A prompt implementation of MOSAIC is feasible, and indeed could increase the robustness and reduce risk on the ELT, since it does not require diffraction limited adaptive optics performance. Science programmes and survey strategies are currently being investigated by the Consortium, which is also hoping to welcome a few new partners in the next two years.
