On-orbit Degradation of the JWST/NIRSpec Micro-Shutter Array: Multiplexing and Target Acquisition
Peter Jakobsen
A statistical analysis of the impact of the diminishing number of operational shutters experienced by the JWST/NIRSpec Micro Shutter Array since Commissioning is presented. It is s…
The James Webb Space Telescope Mission
Jonathan P. Gardner, John C. Mather, Randy Abbott +1004
Twenty-six years ago a small committee report, building on earlier studies, expounded a compelling and poetic vision for the future of astronomy, calling for an infrared-optimized…
The Near-Infrared Spectrograph (NIRSpec) on the James Webb Space Telescope V. Optimal algorithms for planning multi-object spectroscopic observations
N. Bonaventura, P. Jakobsen, P. Ferruit +2
We present an overview of the capabilities and key algorithms employed in the so-called eMPT software suite developed for planning scientifically optimized, multi-object spectrosco…
In-orbit Performance of the Near-Infrared Spectrograph NIRSpec on the James Webb Space Telescope
T. Böker, T. L. Beck, S. M. Birkmann +47
The Near-Infrared Spectrograph (NIRSpec) is one of the four focal plane instruments on the James Webb Space Telescope. In this paper, we summarize the in-orbit performance of NIRSp…
Astrometric and Wavelength Calibration of the NIRSpec Instrument during Commissioning using a model-based approach
Nora Lützgendorf, Giovanna Giardino, Catarina Alves de Oliveira +11
The NIRSpec instrument for the James Webb Space Telescope (JWST) is a highly versatile near-infrared spectrograph that can be operated in various observing modes, slit apertures, a…
Optical throughput and sensitivity of JWST NIRSpec
G. Giardino, R. Bhatawdekar, S. M. Birkmann +13
To achieve its ambitious scientific goals, the Near-Infrared Spectrograph, NIRSpec, on board the Webb Space Telescope, needs to meet very demanding throughput requirements, here qu…
