JWST MIRI flight performance: Detector Effects and Data Reduction Algorithms
Jane Morrison, Daniel Dicken, Ioannis Argyriou +21
The detectors in the Mid-Infrared Instrument (MIRI) of the James Webb Space Telescope (JWST) are arsenic-21 doped silicon impurity band conduction (Si:As IBC) devices and are direc…
The Brighter-Fatter Effect in the JWST MIRI Si:As IBC detectors I. Observations, impact on science, and modelling
Ioannis Argyriou, Craig Lage, George H. Rieke +10
The Mid-Infrared Instrument (MIRI) on board the James Webb Space Telescope (JWST) uses three Si:As impurity band conduction (IBC) detector arrays. The output voltage level of each…
JWST MIRI flight performance: The Medium-Resolution Spectrometer
Ioannis Argyriou, Alistair Glasse, David R. Law +22
The Medium-Resolution Spectrometer (MRS) provides one of the four operating modes of the Mid-Infrared Instrument (MIRI) on board the James Webb Space Telescope (JWST). The MRS is a…
Spectroscopic time series performance of the Mid-Infrared Instrument on the JWST
Jeroen Bouwman, Sarah Kendrew, Thomas P. Greene +21
We present here the first ever mid-infrared spectroscopic time series observation of the transiting exoplanet \object{L 168-9 b} with the Mid-Infrared Instrument (MIRI) on the Jame…
How dark the sky: the JWST backgrounds
Jane R. Rigby, Paul A. Lightsey, Macarena García Marín +17
We describe the sources of stray light and thermal background that affect JWST observations, report actual backgrounds as measured from commissioning and early-science observations…
JWST/MIRI coronagraphic performances as measured on-sky
A. Boccaletti, C. Cossou, P. Baudoz +16
Characterization of directly imaged exoplanets is one of the most eagerly anticipated science functions of the James Webb Space Telescope. MIRI, the mid-IR instrument has the capab…
