AI 中文摘要
麦哲伦红外多目标光谱仪（MIRMOS）将成为智利拉斯坎帕纳斯天文台6.5米麦哲伦望远镜的下一代多目标（MOS）和积分场光谱仪（IFS）。MIRMOS将在0.886 - 2.404微米（Y、J、H和K波段）的同时波长范围内进行R~3700光谱观测，此外还能在0.7 - 0.886微米范围内成像。MOS模式下的目标选择通过低温机制实现，该机制能在13'x3'视场（FoV）内制作多达92个狭缝，可实时重新配置以调整狭缝宽度、更换掩模或形成长狭缝。IFS模式将通过图像切片器式积分场单元（IFU）实现，提供约18"x26"的FoV，由0.84"x26"的切片组成。MIRMOS的设计使其能处理广泛的科学案例，本文将介绍处于初步设计阶段末期的MIRMOS仪器设计。
英文摘要
The Magellan InfraRed Multi-Object Spectrograph (MIRMOS) will be a next generation multi-object (MOS) and integral field spectrograph (IFS) for the 6.5m Magellan telescopes at Las Campanas Observatory in Chile. MIRMOS will perform R~3700 spectroscopy over a simultaneous wavelength range of 0.886-2.404um (Y, J, H, and K bands) in addition to imaging over the range of 0.7-0.886um. Target selection in the MOS mode is achieved through a cryogenic mechanism capable of making up to 92 slits over a 13'x3' field of view (FoV). This mechanism can be reconfigured in real time to adjust slit widths for seeing conditions, change to a different mask, or form a long slit. The IFS mode of operation for MIRMOS will be achieved via an image slicer style integral field unit (IFU) which will provide an ~18"x26" FoV made up of 0.84"x26" slices. MIRMOS's design will allow it to address a wide range of science cases from performing spectroscopy of high-redshift galaxies as well as high signal-to-noise transmission spectroscopy of exoplanet atmospheres with the MOS/long slit mode, while also having the largest FoV IFS operating on a large telescope at these wavelengths. We will describe here the design of the MIRMOS instrument -- now at the end of the preliminary design phase.
