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…
Adaptive optics performance of a simulated coronagraph instrument on a large, segmented space telescope in steady state
Axel Potier, Garreth Ruane, Christopher C. Stark +9
Directly imaging Earth-like exoplanets (``exoEarths'') with a coronagraph instrument on a space telescope requires a stable wavefront with optical path differences limited to tens…
JWST/NIRCam Coronagraphy: Commissioning and First On-Sky Results
Julien H. Girard, Jarron Leisenring, Jens Kammerer +53
In a cold and stable space environment, the James Webb Space Telescope (JWST or "Webb") reaches unprecedented sensitivities at wavelengths beyond 2 microns, serving most fields of…
Contrast performance of an 8m off-axis, segmented space telescope equipped with an adaptive optics system
Axel Potier, Garreth Ruane, Kiarash Tajdaran +9
The Astro2020 decadal survey recommended an infrared, optical, ultra-violet (IR/O/UV) telescope with a 6~m inscribed diameter and equipped with a coronagraph instrument to di…
The Science Performance of JWST as Characterized in Commissioning
Jane Rigby, Marshall Perrin, Michael McElwain +623
This paper characterizes the actual science performance of the James Webb Space Telescope (JWST), as determined from the six month commissioning period. We summarize the performanc…
