Opto-Mechanical Design of ShaneAO: the Adaptive Optics System for the 3-meter Shane Telescope
Christopher Ratliff, Jerry Cabak, Donald Gavel +8
A Cassegrain mounted adaptive optics instrument presents unique challenges for opto-mechanical design. The flexure and temperature tolerances for stability are tighter than those o…
ShaneAO: wide science spectrum adaptive optics system for the Lick Observatory
Donald Gavel, Renate Kupke, Daren Dillon +14
A new high-order adaptive optics system is now being commissioned at the Lick Observatory Shane 3-meter telescope in California. This system uses a high return efficiency sodium be…
Swimming with ShARCS: Comparison of On-sky Sensitivity With Model Predictions for ShaneAO on the Lick Observatory 3-meter Telescope
Srikar Srinath, Rosalie McGurk, Constance Rockosi +10
The Lick Observatory's Shane 3-meter telescope has been upgraded with a new infrared instrument (ShARCS - Shane Adaptive optics infraRed Camera and Spectrograph) and dual-deformabl…
Commissioning ShARCS: the Shane Adaptive optics infraRed Camera-Spectrograph for the Lick Observatory 3-m telescope
Rosalie McGurk, Constance Rockosi, Donald Gavel +16
We describe the design and first-light early science performance of the Shane Adaptive optics infraRed Camera-Spectrograph (ShARCS) on Lick Observatory's 3-m Shane telescope. Desig…
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…
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…
Automated Alignment and On-Sky Performance of the Gemini Planet Imager Coronagraph
Dmitry Savransky, Sandrine J. Thomas, Lisa A. Poyneer +11
The Gemini Planet Imager (GPI) is a next-generation, facility instrument currently being commissioned at the Gemini South observatory. GPI combines an extreme adaptive optics syste…
Gemini Planet Imager Observational Calibrations V: Astrometry and Distortion
Quinn M. Konopacky, Sandrine J. Thomas, Bruce A. Macintosh +24
We present the results of both laboratory and on sky astrometric characterization of the Gemini Planet Imager (GPI). This characterization includes measurement of the pixel scale o…
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…
