Large and Long Programs at Gemini Observatory

Large and long programs (hereafter "large programs" or LLPs) are Principal Investigator-defined and -driven programs that, as a guideline, either require significantly more time than a partner typically approves for a single program or extend over two to six semesters, or both. Large programs are expected to promote collaborations across the partnership's communities, to have significant scientific impact, and normally to provide a homogeneous data set, potentially for more general use. Proposals for Large and Long programs will be accepted annually.

The participating partners (US, Canada, and Argentina) will make available for LLPs up to 20% of their time at each Gemini telescope over each of the next 6 semesters from the start of LLP execution. Principal Investigators (PIs) of LLPs must be based in an institution of one of the participating partner countries. There is no restriction on Co-Investigators. Potential investigators shall be encouraged to collaborate across the participating partnership. The LLPs are designed to enable large multi-partner collaboration programs and/or programs running across multiple semesters to be reviewed within a single time allocation process.

PIs who propose for LLPs have additional requirements, including submission of a letter of intent, development of a management plan, and consideration of added value to the astronomical community through data products, software, or other outcomes; Successful PIs must additionally report on their progress annually.
