Quantum yield and charge diffusion in the Nancy Grace Roman Space Telescope infrared detectors
Jahmour J. Givans, Ami Choi, Anna Porredon +6
The shear signal required for weak lensing analyses is small, so any detector-level effects which distort astronomical images can contaminate the inferred shear. The Nancy Grace Ro…
Properties and characteristics of the WFIRST H4RG-10 detectors
Gregory Mosby, Bernard J. Rauscher, Chris Bennett +16
The Wide-Field Infrared Survey Telescope (WFIRST) will answer fundamental questions about the evolution of dark energy over time and expand the catalog of known exoplanets into new…
Brighter-fatter effect in near-infrared detectors -- III. Fourier-domain treatment of flat field correlations and application to WFIRST
Jenna K. C. Freudenburg, Jahmour J. Givans, Ami Choi +8
Weak gravitational lensing has emerged as a leading probe of the growth of cosmic structure. However, the shear signal is very small and accurate measurement depends critically on…
ACCESS: Enabling an Improved Flux Scale for Astrophysics
Mary Elizabeth Kaiser, Jeffrey W. Kruk, Stephan R. McCandliss +20
Improvements in the precision of the astrophysical flux scale are needed to answer fundamental scientific questions ranging from cosmology to stellar physics. The unexpected discov…
The ^{55}Fe X-ray Energy Response of Mercury Cadmium Telluride Near-Infrared Detector Arrays
Ori D. Fox, Augustyn Waczynski, Yiting Wen +5
A technique involving ^{55}Fe X-rays provides a straightforward method to measure the response of a detector. The detector's response can lead directly to a calculation of the conv…
