论文摘要
我们正在构建一个图像切片机积分场单元（IFU），以在Las Campanas天文台的Magellan Baade望远镜上进行iMacs宽大成像光谱仪，这是重新印度对光学敏感的IMACS增强IFU或Rosie IFU的重新印象。 50.4“ x 53.5”视场将预先切成四个12.6“ x 53.5”子场，然后每个子场将分为21 0.6“ x 53.5”切片。四个主要图像切片机将在iMacs f/2摄像头视野中隔开四个伪截面，从而提供了2000年的频谱分辨率的1800埃斯特罗姆的波长覆盖率。光学器件是手中的。此IFU将实现诸如星云，星系或流出等扩展对象的有效映射，从而使其成为iMacs的强大补充。
We are building an image slicer integral field unit (IFU) to go on the IMACS wide-field imaging spectrograph on the Magellan Baade Telescope at Las Campanas Observatory, the Reformatting Optically-Sensitive IMACS Enhancement IFU, or ROSIE IFU. The 50.4" x 53.5" field of view will be pre-sliced into four 12.6" x 53.5" subfields, and then each subfield will be divided into 21 0.6" x 53.5" slices. The four main image slicers will produce four pseudo-slits spaced six arcminutes apart across the IMACS f/2 camera field of view, providing a wavelength coverage of 1800 Angstroms at a spectral resolution of 2000. Optics are in-hand, the first image slicer is being aluminized, mounts are being designed and fabricated, and software is being written. This IFU will enable the efficient mapping of extended objects such as nebulae, galaxies, or outflows, making it a powerful addition to IMACS.
