Mitigating effects of telescope jitter through differentiable forward-modeling
Max Charles, Louis Desdoigts, Benjamin Pope +3
Instabilities in telescope pointing, commonly referred to as jitter, introduce image degradation that can compromise the accuracy of critical scientific observables. This work pres…
AMIGO: a Data-Driven Calibration of the JWST Interferometer
Louis Desdoigts, Benjamin Pope, Max Charles +8
The James Webb Space Telescope (JWST) hosts a non-redundant Aperture Masking Interferometer (AMI) in its Near Infrared Imager and Slitless Spectrograph (NIRISS) instrument, providi…
Image reconstruction with the JWST Interferometer
Max Charles, Louis Desdoigts, Benjamin Pope +7
Flying on board the James Webb Space Telescope (JWST) above Earth's turbulent atmosphere, the Aperture Masking Interferometer (AMI) on the NIRISS instrument is the highest-resoluti…
The James Webb Interferometer: Space-based interferometric detections of PDS 70 b and c at 4.8 m
Dori Blakely, Doug Johnstone, Gabriele Cugno +22
We observed the planet-hosting system PDS 70 with the James Webb Interferometer, JWST's Aperture Masking Interferometric (AMI) mode within NIRISS. Observing with the F480M filter c…
