GNIRS Ready for Science and IFU Update

Submitted by brian.lemaux on June 14, 2023
  • Read more about GNIRS Ready for Science and IFU Update

GNIRS has been reinstalled on the telescope after the extended shutdown and is ready for science use as of June 6, 2023. All slit spectral modes along with imaging are available. Both the Low Resolution and High Resolution IFUs are now installed and are undergoing commissioning. They will be released for science use at a later date.

First pipeline reduced GHOST observations & available data

Submitted by vkalari on June 9, 2023
  • Read more about First pipeline reduced GHOST observations & available data

We are pleased to present the first GHOST science observations that have been reduced with the GHOST pipeline. We are releasing the spectrum of XX Oph (Be + Red Supergiant; V= 8.59-10.2 mag) as an example to showcase the spectral range, spectral resolution, and overall quality of data that GHOST can provide in standard resolution mode (R=50000; with a total integration time of 240s, and a wavelength range of 347 to 1060nm).

2023B OT Available

The 2023B Gemini Observing Tool is now available for download.

This version is required to access the Gemini Observing Databases.

The Installation Instructions are linked on the Observing Tool web page, and we recommend that everyone download their programs from the databases rather than import from saved XMLs.

May 2023 Fast Turnaround Call for Proposals

Gemini South is accepting proposals for the Fast Turnaround (FT) program.  We are not currently accepting proposals for Gemini North.   Here, we give information specific to this proposal cycle.

DRAGONS Version 3.1 Released

Submitted by david.jones on April 17, 2023
  • Read more about DRAGONS Version 3.1 Released

The latest version of DRAGONS was released on 6 April and includes full support for GMOS long-slit data. With this release, DRAGONS offers support for the science quality reduction of data from the GMOS, NIRI, GSAOI, and F2 imagers, as well as the GMOS long-slit spectrograph (including nod-and-shuffle observations). The 3.1 release also includes new data-reduction recipes, tutorials, interactive tools, an improved calibration manager, GSAOI alignment/stacking (replacing disco_stu), improved procedures for bad-pixel masks, and Python 3.10 compatibility.

GHOST expected Special Call in 2023B, none in 2023A

Submitted by frantaky on March 30, 2023
  • Read more about GHOST expected Special Call in 2023B, none in 2023A

GHOST has not yet been fully commissioned and information such as sensitivities is pending. For this reason GHOST is not offered as an instrument for regular science in 23B. We expect most modes to be fully commissioned late 23A, and for there to be a special Call for proposals in 23B. We will post an announcement as soon as we have more details on the special call in 23B.

Data reduction

The GHOST data reduction pipeline is part of DRAGONS 3.2. Users are recommended to use the instructions provided in the DRAGONS webpages to install and run the pipeline. A tutorial can be found here. 

If you are having issues with your data or data reduction, please contact your program contact scientists, or email ghost_science@noirlab.edu

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.
