Instrument Upgrade Projects: Awarded Proposals

2015 IUP Projects

During the 2015 program cycle, Gemini awarded Professor Casey Papovich from Texas A&M University (USA) for the proposal “Two K-filters for F–2 (K2F2).”  Professor Papovich and his team proposed a small upgrade to F-2 by providing two medium band filters, which split the spectral, range 1.9-2.5 microns.  

The team also includes astronomers from the University of Toronto (Canada), Swinburne University of Technology and Macquarie University (Australia), and Leiden University (Netherlands). The main science case supporting the upgrade use imaging K-band color deep surveys to perform high redshift demography and exploit synergies with current and forthcoming synoptic surveys.  The project envisions other applications as census of low mass stars in high extinction environments. In addition to funding the design, the procurement, and testing of the filters, Gemini has awarded the team with 10 hours of telescope time to demonstrate the scientific benefits of the new capability. The filters are being commissioned and the new capability will be offered to users after November 2017.



2016 IUP Projects

During the 2016 program cycle, Gemini awarded Professor Denise Goncalves from the Federal University of Rio de Janeiro (Brazil) for the proposal “Raman OVI narrow-band imaging with Gemini/GMOS.” The team also includes astronomers from the University of La Serena (Chile), Sejong University (Korea), National Observatory of Brazil, Institute of Earth and Space Sciences (Argentina), and Columbia University (USA). 

The project envisions a promising new technique to discover symbiotic stars in the Local Group of Galaxies by providing a special set of narrow band filters for both GMOS-S and GMOS-N instruments. The symbiotic stars are binary systems in which a dwarf star accretes mass from a red giant companion, possibly the progenitors of one type of supernovae.  In addition to funding the procurement and testing of the filters, Gemini has awarded the team with 10 hours of telescope time to demonstrate the scientific benefits of the new capability. The filters will be commissioned in the last months of 2017 and the new capability will be offered to users after March 2018. Another project was selected from the 2016 proposals, and will be announced soon.
