The Nancy Grace Roman Space Telescope will study the dark matter content of the universe, the expansion history of the universe, and the diversity of exoplanets in the Galaxy using unprecedented wide field infrared surveys. Roman will accomplish this using a focal plane of 18 newly developed HgCdTe detectors. Roman’s detectors, the H4RG-10, are 4K x 4K format 10 micron pixel pitch devices...
HAWAII-4RG (H4RG) detectors will provide a substantial portion of the scientific output for both the Nancy Grace Roman Space Telescope (Roman) and the Prime Focus Spectrograph (PFS) on the Subaru Telescope. In the first half of this talk, I will present my work from the last few years on modeling detector-level effects present in Roman's flight candidates. Specifically, I focus on how these...
The Nancy Grace Roman Space Telescope is a 2.4 m flagship astrophysics mission currently planned for launch in 2026. The secondary Coronagraph Instrument (CGI) shall demonstrate key technologies required for high contrast imaging and spectroscopy of planetary systems, including adaptive optics, high-speed (1 kHz) wavefront sensing and photon counting detectors in the form of Electron...
