One of the main ways that astronomers study the universe is by splitting the telescope light from celestial sources into its component colors. This technique, known as spectroscopy, can often reveal the underlying processes that govern stars, galaxies and the like. A traditional astronomical spectrograph obtains color information at the expense of imaging. However, a modern Integral Field Unit (IFU) spectrograph is able to do both. An IFU obtains an image and a spectrum at each pixel of the image of an astronomical source. The resulting data cube can be studied to determine the spatial distribution of light across a single extended object, or it can be used to study multiple stars or galaxies at once. This project will support the development of an IFU system for the Magellan/Clay telescope at the Las Campanas Observatory. When completed, this instrument will enable a wide range of investigations into topics from the formation of young stars to the dynamics of gas outflows in distant galaxies. In addition to providing a new tool for research, this project will also serve as an essential training opportunity for students and early career scientists. Live feeds from the telescope will be used in conjunction with undergraduate classes. This project builds upon the previous MRI award, 0923160 (PI: Mateo), which funded the development of the Michigan/Magellan Fiber System (M2FS) spectrograph. The M2FS system actually consists of two high-performance optical spectrographs that deliver resolution, R, in the range 1000 to 40,000 over a wavelength range 370-950 nm. Since commissioning in 2013, M2FS has been used to support over 30 distinct science projects proposed by 18 different investigators. This project will develop multi-mode Integral Field Units for Magellan (IFU-M), to be used in conjunction with M2FS. One key design innovation that enables this instrument is the use of fiber gangs, which handle O(10) optical fibers at once for faster fabrication and assembly. Fabrication and assembly will take place at the PI?s lab at the University of Michigan; the completed instrument will be deployed at the Nasmyth focus of the Magellan/Clay telescope at Las Campanas Observatory, where it will undergo commissioning and use as a facility instrument.

天文学家研究宇宙的主要方式之一是将望远镜的光从天体源分解为其成分颜色。 这种称为光谱的技术通常可以揭示控制恒星，星系等的基本过程。 传统的天文光谱仪以牺牲成像为代价获得颜色信息。 但是，现代的积分场单元（IFU）光谱仪都可以同时完成两者。 IFU在天文源图像的每个像素上获得图像和光谱。 可以研究所得的数据立方体，以确定单个扩展对象上光的空间分布，也可以一次用于研究多个恒星或星系。 该项目将支持Las Campanas天文台的麦哲伦/粘土望远镜的IFU系统的开发。 完成后，该仪器将能够对从年轻恒星形成到遥远星系中气体流出动态的主题进行广泛的研究。 除了提供一种新的研究工具外，该项目还将为学生和早期职业科学家提供必不可少的培训机会。望远镜的实时饲料将与本科课程结合使用。 该项目基于先前的MRI奖0923160（PI：MATEO），该奖项资助了密歇根州/麦哲伦光纤系统（M2FS）光谱仪的开发。 M2FS系统实际上由两个高性能光谱仪组成，它们在370-950 nm的波长范围内提供1000至40,000的分辨率R。 自2013年委托以来，M2FS已被用来支持18位不同研究人员提出的30多个不同的科学项目。 该项目将与M2F一起使用麦哲伦（IFU-M）的多模式积分单元（IFU-M）。 一种启用此仪器的关键设计创新是使用纤维帮的使用，该纤维帮派立即处理O（10）光纤以进行更快的制造和组装。 制造和集会将在密歇根大学的PI？S实验室举行；完成的仪器将部署在Las Campanas天文台的Magellan/Clay望远镜的鼻腔焦点上，在那里它将进行调试并用作设施工具。
