Progress on the Gemini High-Resolution Optical SpecTrograph (GHOST) design

摘要

The Gemini High-Resolution Optical SpecTrograph (GHOST) is the newest instrument being developed for the Gemini telescopes, in a collaboration between the Australian Astronomical Observatory (AAO), the NRC -Herzberg in Canada and the Australian National University (ANU). We describe the process of design optimisation that utilizes the unique strengths of the new partner, NRC - Herzberg, the design and need for the slit viewing camera system, and we describe a simplification for the lenslet-based slit reformatting. Finally, we outline the updated project plan, and describe the unique scientific role this instrument will have in an international context, from exoplanets through to the distant Universe.
