On-sky low order non-common path correction of the GPI Calibration Unit
Markus Hartung, Bruce Macintosh, Paul Langlois +12
The Gemini Planet Imager (GPI) entered on-sky commissioning phase, and had its First Light at the Gemini South telescope in November 2013. Meanwhile, the fast loops for atmospheric…
On-sky vibration environment for the Gemini Planet Imager and mitigation effort
Markus Hartung, Tom Hayward, Les Saddlemyer +20
The Gemini Planet Imager (GPI) entered on-sky commissioning and had its first-light at the Gemini South (GS) telescope in November 2013. GPI is an extreme adaptive optics (XAO), hi…
Effects of differential wavefront sensor bias drifts on high contrast imaging
Naru Sadakuni, Bruce A. Macintosh, David W. Palmer +11
The Gemini Planet Imager (GPI) is a new facility, extreme adaptive optics (AO), coronagraphic instrument, currently being integrated onto the 8-meter Gemini South telescope, with t…
The Integral Field Spectrograph for the Gemini Planet Imager
James E. Larkin, Jeffrey K. Chilcote, Theodore Aliado +31
The Gemini Planet Imager (GPI) is a complex optical system designed to directly detect the self-emission of young planets within two arcseconds of their host stars. After suppressi…
Gemini Planet Imager One Button Approach
Jennifer Dunn, Dan Kerley, Leslie Saddlemyer +9
The Gemini Planet Imager (GPI) is an "extreme" adaptive optics coronagraph system that is now on the Gemini South telescope in Chile. This instrument is composed of three different…
Gemini Planet Imager Observational Calibrations I: Overview of the GPI Data Reduction Pipeline
Marshall D. Perrin, Jérôme Maire, Patrick Ingraham +35
The Gemini Planet Imager (GPI) has as its science instrument an infrared integral field spectrograph/polarimeter (IFS). Integral field spectrographs are scientificially powerful bu…
On-sky performance during verification and commissioning of the Gemini Planet Imager's adaptive optics system
Lisa A. Poyneer, Robert J. De Rosa, Bruce Macintosh +15
The Gemini Planet Imager instrument's adaptive optics (AO) subsystem was designed specifically to facilitate high-contrast imaging. It features several new technologies, including…
