Abstract / Description:The James Webb Space Telescope (JWST) will be one of the great observatories of the next decade. NIRSpec (Near Infrared Spectrograph) is the near-infrared multi-object spectrograph of the JWST and it features a 3"×3" Integral Field Unit, a set of high-contrast fixed slits, and 730×342 individually addressable shutters of 0.2" (width) ×0.5" (cross-dispersion), covering a 9 arcmin2 field for multi-object spectroscopy in the wavelength range 0.6-5.0 μm, at a spectral resolution of 100-1000. The instrument is already integrated in the JWST payload module and has recently undergone a series of detailed calibration tests in a cryogenic environment, confirming its excellent capabilities. Here we provide an overview of the MOS mode of NIRSpec and its performance, and discuss how the combination of NIRSpec multiplexing and high sensitivity will allow observations of thousands of galaxies throughout a wide redshift range (typically 2-8) to be obtained, shedding new light onto the physics of galaxy assembly and evolution.
