Estimating effective wind speed from Gemini Planet Imager's adaptive optics data using covariance maps
Daniel M. Levinstein, Saavidra Perera, Quinn M. Konopacky +4
The Earth's turbulent atmosphere results in speckled and blurred images of astronomical objects when observed by ground based visible and near-infrared telescopes. Adaptive optics…
GPI 2.0: Optical Designs for the Upgrade of the Gemini Planet Imager Coronagraphic system
Meiji M. Nguyen, Bryony F. Nickson, Emiel H. Por +7
The Gemini Planet Imager (GPI) is an integral field spectrograph (IFS) and coronagraph that is one of the few current generation instruments optimized for high-contrast direct imag…
Integral field spectroscopy with the solar gravitational lens
Alexander Madurowicz, Bruce Macintosh
The prospect of combining integral field spectroscopy with the solar gravitational lens (SGL) to spectrally and spatially resolve the surfaces and atmospheres of extrasolar planets…
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…
