  1. Collaboration status between ASIAA and Subaru Shiang-Yu Wang (王祥宇) Institute of Astronomy and Astrophysics Academia Sinica

  2. Hyper SuprimeCam • Fits the interests of ASIAA both in the technical and science aspects • Discussions for the collaboration began in late 2006 • Funding for HSC-Taiwan secured in 2008 • MOU signed Oct 2008

  3. Technical participation in HSC • Mechanical Shutter (ASRD) • Filter exchanger (ASRD) • CCD procurement and test • Lens testing system (GEOS) • Data reduction software? Fit the needs of the project Learn new technology from the development Brought in the local companies to help

  4. Mechanical shutter • Major change of the allowed dimensions in Aug 2008. • Prototyping stopped • Activity transferred to NAOJ • New prototype under tests.

  5. Filter exchanger Separated filter exchanger unit is designed to solve the space and weight constrain

  6. Specification for FEU • Number of filters: 6 filters • Minimum operational life of filter: 40,000 cycles • Minimum time between maintenance: 4,000 cycles • Max time between two visits in different filters: 10 min (goal 5 min) • Accommodate SH filter • Filter glass aperture: ϕ600mm • Filter glass thickness: 28mm • position reproducibility : 50 micron • Weight: 240+/-40 kg

  7. FEU centering mechanism

  8. Lens testing system • Test the lens with two different configurations

  9. Expected Schedule • Complete detailed design of FEU in March 2009 • First CCD chip to be delivered in March 2009 • Lens testing system completed in Feb 2010 • Delivery of FEU in mid 2010

  10. Scientific interests • Enhance the collaboration between Japanese and Taiwanese astronomers to use the Subaru telescope • Participate in the HSC survey • Mini workshop held in Dec 2008

  11. Interests on HSC survey • Enrich the existing research topics • Weak lensing survey (Umestu, Nishioka) • High z galaxies study (Lin, Hsieh, Wang) • GRB & SNa study (Huang, Urata) • Solar system (Abe) • Synergy with on-going projects in Taiwan: • AMiBA • ALMA • TAOS • PanSTARRS

  12. Interests on HSC survey • Enrich the existing research topics • Weak lensing survey (Umestu, Nishioka) • High z galaxies study (Lin, Hsieh, Wang) • GRB & SNa study (Huang, Urata) • Solar system (Abe) • Synergy with on-going projects in Taiwan: • AMiBA • ALMA • TAOS • PanSTARRS

  13. AMiBA (Array for Microwave background Anisotropy) • SZE interferometer • 13 elements implemented in 2009 • Increasing the photon-collecting area by a factor of ~7.4 • Angular resolution is 2 arcmin (10’ FoV)

  14. Simulated AMiBA and Subaru Surveys Subaru WL ng=30 arcmin^-2 zs=1 s(g)=0.4 AMiBA13 SZE

  15. TAOS (Taiwan America Occultation Survey) • 4 Robotic telescopes for the search of stellar occultation by KBO and EDOs.
