NIRI

Gemini NorthNear-IR
Last Modified: 
Monday, April 11, 2022 - 12:49

NIRI is used as the main NIR imager at Gemini North. It has three cameras, and a large number of broad- and narrow band filters are available. The Gemini facility adaptive optics (AO) system, ALTAIR, (either with a natural guide star or the laser guide star), is available for use with NIRI f/32 for J-L' imaging and NIRI f/14 for imaging out to 2.5 microns. The advantage of AO at L' is modest and is only for point sources.

Available For Proposals at Gemini North
For more details, see the schedules and the CfPs.

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.
