Webb28 maj 2024 · The science goals of JWST require a versatile mid-infrared instrument covering the 5-28.5 μm wavelength range with a wide field of view for imaging through broad and narrow band filters, low resolution spectroscopy from 5-10 μm, moderate resolution spectroscopy with R ~ 3000, and high dynamic range coronography. WebbWebbPSF is a Python package that computes simulated point spread functions (PSFs) for NASA’s James Webb Space Telescope (JWST) and Nancy Grace Roman Space … WebbEven so, the MRS provides an adequate angular resolution to separate the nuclear and circumnuclear regions in NGC 6552.
