Enhancing Astronomy Collaboration for Better Science

Learn about the importance of collaboration in astronomy for better science, budgetary limitations, and partnerships in East Asia and the EU. Discover how institutions like Princeton University and ASIAA are contributing to projects like Subaru Telescope. The session with Subaru users, PU, and ASIAA representatives aims to solidify collaborations and foster trust among optical-infrared astronomers.

  1. International Collaboration Masa Hayashi Subaru Users’ Meeting January 31, 2008

  2. Why Collaboration? • Better science through collaboration • If you want to do a big survey, you need to benefit (or persuade) many scientists. (Democratic nature of open-use facility) • Budgetary limitations • HSC would not be realized without funding contributions from collaborating institutes (NAOJ approved the HSC grant-in-aid proposal submission emphasizing that no funding is available from the NAOJ ordinary operation budget) • Collaboration in East Asia • Regional collaborations in EU and NA have been going well, and why not in East Asia? (Radio astronomers are doing well now). • Political situation for big projects: CSTP questioned (before Taiwan came to join ALMA-J) why Japan participated in ALMA as a single country different from EU and NA.

  3. MPIA • 2005 • MPIA expressed intention to develop an infrared wave front sensor for AO188 • August 2006 • Letter of Understanding concluded • March 2007 • NAOJ Director-General and Subaru Director visited MPIA • Exchanging researchers as a next step for further collaboration

  4. Princeton University • Dec 2006 • PU sent a delegation to NAOJ/Subaru to discuss possible collaboration on HSC and HiCIAO. • Jan 2007 • “Letter of Interest” sent from NAOJ Director-General to PU • June 2007 • NAOJ-PU meeting for an MOU • Sep 2007 • SAC chair and Subaru Director visited PU for MOU details.

  5. Points of NAOJ-PU MOU • Science collaboration in wide areas of astronomy and astrophysics using Subaru Telescope, extending a decade-long collaboration between Japanese and PU astronomers. • PU will contribute US$10M to NAOJ for the top unit modification necessary for HSC. • NAOJ will allocate at least 100 nights of observing time for Japan-PU joint Strategic Observing Programs with HSC and/or HiCIAO if they were accepted by SAC. • 10 years

  6. ASIAA • Aug 2005 • Subaru director (Karoji) visited ASIAA • Discussion on possible contribution from ASIAA to HSC • Feb 2006 • Dr. Wang visited Subaru • Discussion on possible ASIAA’s contribution to HSC fabrication • Mar 2006 • Collaboration with NAOJ/Subaru was proposed at the board meeting • Technical contribution to HSC fabrication • Increase optical-infrared astronomers at ASIAA for science collaboration — July 2006: HSC grant-in-aid proposal approved— • Mar 2007 • Subaru director (Hayashi) expressed intention to promote Subaru-ASIAA collaboration on optical-infrared astronomy at the ASIAA board meeting

  7. Points of NAOJ-ASIAA MOU • Collaboration on HSC (ongoing) • Participate in the HSC development and fabrication • Funding contribution to HSC fabrication • Access to Subaru via collaborations (HSC, AO, ...) • 5-10 years? • Establish trust among optical-infrared astronomers in both parties

  8. The Meaning of This Session • Direct interaction of Subaru users with expected collaboration partners (PU and ASIAA) • Subaru’s user community receives detailed information from PU and ASIAA representatives • Last chance for Subaru users to express themselves before MOU
