GMTNIRS (Giant Magellan Telescope near-infrared spectrograph): design concept

Abstract: We are designing a sensitive high resolution (R=60,000-100,000) spectrograph for the Giant Magellan Telescope (GMTNIRS, the GMT Near-Infrared Spectrograph). Using large-format IR arrays and silicon immersion gratings, this instrument will cover all of the J (longer than 1.1 μm), H, and K atmospheric windows or all of the L and M windows in a single exposure. GMTNIRS makes use of the GMT adaptive optics system for all bands. The small slits will offer the possibility of spatially resolved spectroscopy as well a… Show more

“…Alternatively, the HIRES spectrograph 41 is expected to cover the optical to nearinfrared wavelength regime, and can be used for this type of observation, if it is designed with a slit or with multiple fibers that can cover both the star and the planet. The other Extremely Large Telescope projects, the Giant Magellan Telescope 42 and the Thirty Meter Telescope 43 , also have optical and infrared high-resolution spectrographs in their instrument roadmaps.…”

“…Work on MANIFEST is being pursued at a moderate level of effort, in order to investigate the key interface issues with the instrument designs as well as with the telescope. The GMT instrument program is discussed in greater detail by Dan Jaffe, 16 one of the instruments (GMTNIRS) is described by Lee et al, 17 and the concept for MANIFEST is presented by Saunders et al 18 …”
