Micro-arcsecond Astrometry Technology: Detector and Field Distortion Calibration
Michael Shao, Chengxing Zhai, Bijan Nemati +3
Microarcsecond (uas) astrometry is an indispensable technique to detect earth-like exoplanets, fully characterize exoplanetary orbits, and measure their masses --information critic…
Simulating reflected light coronagraphy of Earth-like exoplanets with a large IR/O/UV space telescope: impact and calibration of smooth exozodiacal dust
Jens Kammerer, Christopher C. Stark, Kevin J. Ludwick +2
Observing Earth-like exoplanets orbiting within the habitable zone of Sun-like stars and studying their atmospheres in reflected starlight requires contrasts of $\sim1\mathrm{e}{-1…
Flatfield Calibrations with Astrophysical Sources for the Nancy Grace Roman Space Telescope's Coronagraph Instrument
Erin R. Maier, Robert T. Zellem, M. Mark Colavita +12
The Nancy Grace Roman Space Telescope Coronagraph Instrument is a high-contrast imager, polarimeter, and spectrometer that will enable the study of exoplanets and circumstellar dis…
Nancy Grace Roman Space Telescope Coronagraph Instrument Observation Calibration Plan
Robert T. Zellem, Bijan Nemati, Guillermo Gonzalez +20
NASA's next flagship mission, the Nancy Grace Roman Space Telescope, is a 2.4-meter observatory set to launch no later than May 2027. Roman features two instruments: the Wide Field…
