MagNIFIES: Background

MagNIFIES is the Magellans' Near-Infrared Five-band Immersion grating Efficient Spectrograph which will be built by the KASI and the University of Texas at Austin (UT). The MagNIFIES is a project to bring the GMT instrument GMTNIRS to Magellan before GMT needs it. This spectrograph gives a lot of scientific potential with its spectral resolution of 40,000 - 50,000 and the largest simultaneous spectral grasp (1-5 microns) of any high-resolution spectrograph in the world in a single exposure ? the entire spectrum transmitted through the Earth's atmosphere.

KASI and UT collaboration team presented a conceptual design for the GMTNIRS, and it has been reviewed by a panel of experts. The GMTO (GMT Organization) selected the GMTNIRS as a first-generation instrument of the GMT according to the panel's decision. The GMTNIRS will be an adaptive optics instrument, but the GMT will be operated in natural seeing mode until 2028 due to the project's circumstances. In response to current status, the KASI-UT team proposed the MagNIFIES which can be attached to 6.5m-Magellan telescope and is based on the IGRINS heritage and the conceptual design of the GMTNIRS.
