The Nancy Grace Roman Space Telescope Wide Field Instrument: Characterization of the Brighter-Fatter Effect in a Roman H4RG-10 Detector using the Talbot Effect
Jennie Paine, Ami Choi, Christopher Merchant +14
The Nancy Grace Roman Space Telescope will conduct several community-driven surveys using its Wide Field Instrument (WFI), which contains 18 Teledyne H4RG-10 near-infrared detector…
Simulating image coaddition with the Nancy Grace Roman Space Telescope: II. Analysis of the simulated images and implications for weak lensing
Masaya Yamamoto, Katherine Laliotis, Emily Macbeth +16
One challenge for applying current weak lensing analysis tools to the Nancy Grace Roman Space Telescope is that individual images will be undersampled. Our companion paper presente…
Simulating image coaddition with the Nancy Grace Roman Space Telescope: I. Simulation methodology and general results
Christopher M. Hirata, Masaya Yamamoto, Katherine Laliotis +16
The upcoming Nancy Grace Roman Space Telescope will carry out a wide-area survey in the near infrared. A key science objective is the measurement of cosmic structure via weak gravi…
A Joint Roman Space Telescope and Rubin Observatory Synthetic Wide-Field Imaging Survey
M. A. Troxel, C. Lin, A. Park +22
We present and validate 20 deg of overlapping synthetic imaging surveys representing the full depth of the Nancy Grace Roman Space Telescope High-Latitude Imaging Survey (HLIS)…
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…
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…
