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…
ESA Voyage 2050 White Paper: Detecting life outside our solar system with a large high-contrast-imaging mission
Ignas Snellen, Simon Albrecht, Guillem Anglada-Escude +64
In this white paper, we recommend the European Space Agency plays a proactive role in developing a global collaborative effort to construct a large high-contrast imaging space tele…
The Inner Disk Structure, Disk-Planet Interactions, and Temporal Evolution in the Beta Pictoris System: A Two-Epoch HST/STIS Coronagraphic Study
Daniel Apai, Glenn Schneider, Carol A. Grady +5
We present deep HST/STIS coronagraphic images of the Beta Pic debris disk obtained at two epochs separated by 15 years. The new images and the re-reduction of the 1997 data provide…
