JWST NIRCam Defocused Imaging: Photometric Stability Performance and How it Can Sense Mirror Tilts
Everett Schlawin, Thomas Beatty, Brian Brooks +25
We use JWST NIRCam short wavelength photometry to capture a transit lightcurve of the exoplanet HAT-P-14 b to assess performance as part of instrument commissioning. The short wave…
The Near Infrared Imager and Slitless Spectrograph for the James Webb Space Telescope -- IV. Aperture Masking Interferometry
Anand Sivaramakrishnan, Peter Tuthill, James P. Lloyd +36
The James Webb Space Telescope's Near Infrared Imager and Slitless Spectrograph (JWST-NIRISS) flies a 7-hole non-redundant mask (NRM), the first such interferometer in space, opera…
The Near Infrared Imager and Slitless Spectrograph for JWST -- V. Kernel Phase Imaging and Data Analysis
Jens Kammerer, Rachel A. Cooper, Thomas Vandal +26
Kernel phase imaging (KPI) enables the direct detection of substellar companions and circumstellar dust close to and below the classical (Rayleigh) diffraction limit. We present a…
APLC-Optimization: an apodized pupil Lyot coronagraph design survey toolkit
Bryony F. Nickson, Emiel H. Por, Meiji M. Nguyen +9
We present a publicly available software package developed for exploring apodized pupil Lyot coronagraph (APLC) solutions for various telescope architectures. In particular, the pa…
GPI 2.0: Optical Designs for the Upgrade of the Gemini Planet Imager Coronagraphic system
Meiji M. Nguyen, Bryony F. Nickson, Emiel H. Por +7
The Gemini Planet Imager (GPI) is an integral field spectrograph (IFS) and coronagraph that is one of the few current generation instruments optimized for high-contrast direct imag…
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…
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…
Low-order wavefront control using a Zernike sensor through Lyot coronagraphs for exoplanet imaging
R. Pourcelot, M. N'Diaye, E. H. Por +19
Combining large segmented space telescopes, coronagraphy and wavefront control methods is a promising solution to produce a dark hole (DH) region in the coronagraphic image of an o…
