High-contrast imager for complex aperture telescopes (HiCAT): 8. Dark zone demonstration with simultaneous closed-loop low-order wavefront sensing and control
Rémi Soummer, Emiel H. Por, Raphaël Pourcelot +27
We present recent laboratory results demonstrating high-contrast coronagraphy for the future space-based large IR/Optical/Ultraviolet telescope recommended by the Decadal Survey. T…
A Year of Wavefront Sensing with JWST in Flight: Cycle 1 Telescope Monitoring and Maintenance Summary
Charles-Philippe Lajoie, Matthew Lallo, Marcio Meléndez +7
We summarize JWST's measured telescope performance across science Cycle 1. The stability of segments alignments is typically better than 10 nanometers RMS between measurements ever…
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 James Webb Space Telescope Mission: Optical Telescope Element Design, Development, and Performance
Michael W. McElwain, Lee D. Feinberg, Marshall D. Perrin +126
The James Webb Space Telescope (JWST) is a large, infrared space telescope that has recently started its science program which will enable breakthroughs in astrophysics and planeta…
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…
High-contrast imager for complex aperture telescopes (HiCAT): 5. first results with segmented-aperture coronagraph and wavefront control
Remi Soummer, Gregory R. Brady, Keira Brooks +19
Segmented telescopes are a possibility to enable large-aperture space telescopes for the direct imaging and spectroscopy of habitable worlds. However, the complexity of their apert…
High-contrast Imager for Complex Aperture Telescopes (HiCAT): 6. Software Control Infrastructure and Calibration
Christopher Moriarty, Keira Brooks, Remi Soummer +5
High contrast imaging using coronagraphy is one of the main avenues to enable the search for life on extrasolar Earth analogs. The HiCAT testbed aims to demonstrate coronagraphy an…
Phase-Retrieval-Based Wavefront Metrology for High Contrast Coronagraphy
Gregory R. Brady, Christopher Moriarty, Peter Petrone +5
We discuss the use of parametric phase-diverse phase retrieval as an in-situ high-fidelity wavefront measurement method to characterize and optimize the transmitted wavefront of a…
