8 Scientific Committee on Antarctic Research Astronomy & Astrophysics from Antarctica (AAA) Proposal to establish the AAA Scientific Research Programme VERSION: 18 June 2008 Expected Duration: 2008 – 2012 Estimated SCAR funding: $US60,000

9 Astronomy & Astrophysics from Antarctica Scientific Research Programme Broadly stated, the objectives of Astronomy & Astrophysics from Antarctica are to coordinate astronomical activities in Antarctica in a way that ensures the best possible outcomes from international investment in Antarctic astronomy, and maximizes the opportunities for productive interaction with other disciplines.

10 Astronomy & Astrophysics from Antarctica Scientific Research Programme Deliverable outcomes, including public awareness We aim to deliver: Quantitative assessments of the potential of each Antarctic plateau station to contribute to astronomy, Advances in the understanding of Antarctic meteorology, as it applies to astronomical observations, Improved coordination with atmospheric and ionospheric researchers, Papers in peer-reviewed journals, Properly archived data sets of site-testing data.

28 Coordinate site-testing experiments to ensure that results obtained from different sites are directly comparable and well understood, Build a data base of site-testing data that is accessible to all researchers, Increase the level of coordination and cooperation between astronomers, atmospheric physicists, space physicists and meteorologists, Extend existing Antarctic site-testing and feasibility studies to potential Arctic sites; for example, in Greenland and Canada, Define and prioritise current scientific goals, Create a roadmap for development of major astronomical facilities in Antarctica, Stimulate international cooperation on major new astronomical facilities in Antarctica.

30 Polar Auroras Dempsey et al, PASA, 2005 Median sky brightness contribution at Dome C in B and V ~22 mag/square arcsec (comparable to zodiacal light).

31 Astronomy & Astrophysics from Antarctica Scientific Research Programme By mid 2010 Comparative site-testing data obtained from Dome C, Dome A, and Dome F, base-lined against South Pole data Input provided to the ARENA final report, and to the PILOT design study Site testing commenced at sites in Greenland and northern Canada.

32 Astronomy & Astrophysics from Antarctica Scientific Research Programme By mid 2012 Web based archive of site testing data from all sites, fully publicly accessible, At least one major (>$50m) new international astronomical facility approved for construction, with approval based in part on Astronomy & Astrophysics from Antarctica recommendations, Roadmap in place for future astronomical facilities

33 Astronomy & Astrophysics from Antarctica Scientific Research Programme Beyond 2012 The Astronomy & Astrophysics from Antarctica SRP is proposed for a period of four years only in the first instance. If it is meeting all of its milestones at this time, including the successful coordination of major new astronomical facilities in Antarctica, a new proposal for its continued operation will be submitted.

34 Astronomy & Astrophysics from Antarctica Scientific Research Programme 8. Success factors Published results in refereed journals, Higher visibility both for SCAR and for Antarctic astronomy, as measured by increased numbers of positive media reports, Greater cooperation with atmospheric, meteorological and ionospheric researchers, as evidenced by increased numbers of interdisciplinary publications and cross-discipline citations, Systematic programs site-testing of Arctic sites established, with close links to new and existing Antarctic programs, Astronomy & Astrophysics from Antarctica results and recommendations used by builders and planners of major new astronomical facilities in Antarctica.

35 Astronomy & Astrophysics from Antarctica Scientific Research Programme Four Themes A. Site testing, validation and data archiving. B. Arctic site testing. C. Science goals. D. Major new facilities.

36 Ongoing or planned site-testing Dome A – seeing – turbulence profiling – surface layer profiling – optical photometry – cloud cover – submm transparency Dome C – seeing – optical photometry – cloud cover – submm transparency Dome F – seeing – surface-layer profiling – IR sky brightness Summit station, Greenland – seeing – cloud cover Ellesmere Island, Canada – cloud cover

37 Updated time-line July 2008 – Seek approval of SRP proposal at Delegates meeting During 2009 – Official launch (IYA event) – Select theme leaders and working groups – Develop implementation plan 2010 – Funded program begins Mid 2010 – Presentation at SCAR XXXI Mid 2012 – Review – Presentation at SCAR XXXII Astronomy & Astrophysics from Antarctica Scientific Research Programme
