Gemini e-Newscast #78

In This e-Newscast:

Low Spin Produces Clumpy Galaxies

A team of Australian researchers used two Maunakea-based observatories – Gemini North and W. M. Keck Observatory – to discover why some galaxies are clumpy rather than spiral. They concluded that low specific angular momentum is primarily responsible for the clumpiness (and corresponding star formation) rather than large amounts of gas as previously suggested. Danail Obreschkow (International Centre for Radio Astronomy Research, University of Western Australia) led the research which also suggests that angular momentum is the key difference between more distant (z~2) clumpy galaxies similar to the low-redshift sample of this work, and spiral galaxies in the local universe. More information is posted on the Gemini web page, and full results are published in The Astrophysical Journal.
The massive star-forming galaxies of this study have clumpy, turbulent gas. Integral field spectroscopy with GMOS and other instruments yielded kinematic measurements.

January 8: Gemini Town Hall at the AAS 

Gemini will host a Town Hall during the upcoming American Astronomical Society (AAS) meeting in Kissimmee, Florida. Join us on Friday, January 8, 2016, 12:45-1:45PM in the Tampa Room, where you can hear the latest news and provide your feedback about Gemini. Staff will be available to answer questions and to provide user support at the booth (at NSF pavilion) in the exhibit hall throughout the meeting.

GIFS Study Reports Posted

The reports from the Gemini Instrument Feasibility Studies (GIFS) are posted; see the links at the Gemini web pages. These studies will inform the requirements for Gemini’s next facility instrument, known as “Generation 4, number 3” or “Gen4#3.”  We also welcome additional feedback from our user community, on any aspect of science, requirements, technical capability, or design of the new instrument. Send your thoughts directly to by January 22, 2016. The call for proposals for Gen4#3 will be released during 2016 Q2 and will be open to all proposers, independent of participation in the earlier feasibility studies. 

Next Fast Turnaround Deadline is December 31

Celebrate the end of the year with a proposal for the Fast Turnaround program. The next deadline is December 31, 2015, for observations beginning in February 2016. Instruments on both the Gemini North and South telescopes are available for use. Full details of this month’s call for proposals are posted. To receive monthly deadline reminders and news of changes to the program that may affect or interest potential users, send a message to

Use the New Gemini Observatory Archive

Join over 150 other registered users of the new Gemini Observatory Archive (GOA) at You will need to register in order to access proprietary data, using your Gemini program ID and the program key from your time award email. More information on this process is posted at: You can also use the GOA without registration to obtain public data. The GOA is now the primary conduit to obtain data from Gemini.
