Gemini SouthNear-IR
Last Modified: 
Tuesday, April 8, 2025 - 07:20

The Gemini South Adaptive Optics Imager (GSAOI) is a near-infrared adaptive optics camera used with the Gemini Multi-conjugate Adaptive Optics System (GeMS) on Gemini South. It provides near-diffraction limited images in the 0.9 - 2.4 μm wavelength range. In the adaptive optic sense, GSAOI is a wide-field imaging system with a 4080 x 4080 pixel detector format.

Temporarily Unavailable For Proposals at Gemini South

International Gemini Observatory

The International Gemini Observatory  provides the astronomical communities in six participant countries with state-of-the-art astronomical facilities that allocate observing time in proportion to each country's contribution. In addition to financial support, each country also contributes significant scientific and technical resources. The national research agencies that form the Gemini partnership include: the US National Science Foundation (NSF), the Canadian National Research Council (NRC), the Chilean Agencia Nacional de Investigación y Desarrollo (ANID), the Brazilian Ministério da Ciência, Tecnologia e Inovação, the Argentinean Ministerio de Ciencia, Tecnología e Innovación, and the Korea Astronomy and Space Institute (KASI). The observatory is managed by the Association of Universities for Research in Astronomy, Inc. (AURA) under a cooperative agreement with the NSF. The NSF also serves as the executive agency for the international partnership.
