Développement d'un simulateur de performances pour le spectrographe NIRSpec du futur télescope spatial JWST. (JWST/NIRSpec Instrument Performace Simulator)
The near-infrared multi-object spectrograph NIRSpec is one of the three science instruments onboard the future James Webb Space Telescope. NIRSpec will cover the 0.6 to 5.0 μm wavelength range and will be able to obtain simultaneous spectra of more than 100 objects in a 9 square arcminute field of view, thanks to an array of micro-shutters. It has been realized that accurate modelling of the in...
متن کاملCalibration concept for the JWST Near - infrared Spectrograph ( NIRSpec )
This document provides a discussion of the basic calibration needs and calibration time consumption for the Near Infrared Spectrograph (NIRSpec) on JWST. The current version assumes that slits for multi object spectroscopy will be formed via a microelectromechanical system and that NIRSpec will carry internal continuum and line lamps.
متن کاملComparison of Super-Sky and Self-Calibration Flat Fields for Simulated Mid-Infrared JWST Images
The efficacy of two different flat-field calibration methods for JWST are considered. Flat fields obtained by the co-addition of sky flats and those obtained via self-calibration are quantitatively compared. Both methods can produce flat fields with an accuracy of a few parts in 105 that satisfy the JWST science requirements, as long as the instrumental response and background properties remain...

متن کاملMicroshutters Arrays for the JWST Near Infrared Spectrograph
The Near Infrared Spectrograph (NIRSpec) for the James Webb Space Telescope (JWST) is a multi-object spectrograph operating in the 0.6-5.0 μm spectral range. One of the primary scientific objectives of this instrument is to measure the number and density evolution of galaxies following the epoch of initial formation. NIRSpec is designed to allow simultaneous observation of a large number of sou...
