GHOST Progress on Cerro Pachón

The Gemini High-resolution Optical SpecTrograph (GHOST) instrument is expected to play a vital role in the research output of Gemini South in the 2020s. GHOST is built by a collaboration between Australian Astronomical Optics, the Australian National University, and the National Research Council Canada’s Herzberg Astronomy and Astrophysics Research Center. It is designed to be efficient, versatile, and to have wide wavelength coverage. This means GHOST can be used for a broad range of applications which include understanding the chemical evolution of the Universe and our galaxy as well as the confirmation and characterization of exoplanet systems. This new instrument will also provide crucial follow-up of interesting targets from many ongoing and future surveys like the Vera C. Rubin Observatory’s Legacy Survey of Space and Time (LSST).
