The Magellan Infrared Multi-object Spectrograph (MIRMOS) is a near-infrared (NIR) multi-object spectrograph (MOS) and integral field unit (IFU) to be deployed at the Magellan 6.5-meter telescopes at Las Campanas Observatory. MIRMOS is designed to address frontier scientific questions in extragalactic and exoplanetary science. Specific key science cases include:
- Mapping the topology of late reionization by detecting Lyα and metal line emission from z > 7 galaxies
- Delineating the connection between galaxies and the cosmic web by measuring galaxy properties and large-scale environments at cosmic noon (1.5<z<3)
- Imaging the circumgalactic medium in emission
- Conducting a census of exoplanet atmospheres by achieving very high spectrophotometric precision.
MIRMOS will be the only MOS on a 6.5-10 m telescope to observe the full NIR spectrum from 0.95-2.5 μm simultaneously. The spectrograph can be fed by a mechanical slit mask capable of deploying up to 120 slits over a 13' × 3' field, or by an image slicer IFU with a wide field of 26' × 10'. MIRMOS will be the only second-generation NIR MOS at any large U.S.-based telescope and the only wide-field NIR IFU on any 6.5-10 m telescope worldwide.
