IGRINS

Gemini SouthNear-IR
Last Modified:

IGRINS (Immersion GRating INfrared Spectrometer) is a visiting instrument available at Gemini South. It is a compact high-resolution near-infrared spectrograph that primarily disperses light with a silicon immersion grating. Individual volume phase holographic (VPH) gratings serve as cross-dispersing elements for separate spectrograph arms covering the H and K bands. IGRINS observations cover the entire wavelength range between 1.45 and 2.45μm, and do so in a single exposure with a resolving power of R~45,000. As there are no moving cryogenic parts, all observations have the same spectral format.

International Gemini Observatory Participants

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.
