Led by Bruce Macintosh (LLNL), the GPI project is a large collaboration involving the American Museum of Natural History, the Herzberg Institute of Astrophysics, JPL, the Univ. of Montreal, the Institut National d’Optique, UCB, UCSC/UCO and UCLA. This instrument is designed for direct imaging and low-resolution spectroscopy of young planets around nearby stars using high-contrast (extreme) AO. GPI will be located at the Cassegrain focus of the Gemini South 8-m telescope on Cerro Pachon, Chile. UCLA (James Larkin) will provide the back-end instrument.
