Abstract

The Gemini Infrared Multi-Object Spectrograph (GIRMOS) is a four-channel adaptive-optics-assisted integral field spectrograph under design for the Gemini North Telescope. It will be employed behind the Gemini North Adaptive Optics System and will provide additional adaptive optics correction in each spectroscopic channel. This will provide multi-object spectroscopy between 0.9-2.4 µm in four fields with resolution near the diffraction limit. In addition to its spectroscopic capabilities, GIRMOS will employ an imaging camera that will provide photometry of the field of regard. The main science objectives of GIRMOS include the mapping of chemical abundances, star formation and kinematics in high-redshift galaxies, and studies of stellar populations, star formation, and super-massive black holes in nearby galaxies. In this paper, we summarize the preliminary design of the GIRMOS Calibration System that will enable spectroscopic, photometric and astrometric calibration.
