  1. Canadian Virtual Observatory Project David Schade Canadian Astronomy Data Centre Herzberg Institute for Astrophysics National Research Council Canada

  2. Canadian Astronomy Data Center Formed in 1986 • Partner in many success stories • Hubble Space Telescope • Development of the model for the contemporary data centre • Multi-wavelength/Multi-observatory • Leader in Virtual Observatory movement • Canadian Legacy Surveys • State-of-the-Art Science Data Management is an integral part of these projects • Current Holdings 112 Terabytes • Total traffic in/out: 12.1 Tbytes in past month

  3. Canadian Astronomy Data Center • CFHT Legacy Surveys • SuperNovae: Dark Energy • Mass Distribution from Gravitational Lensing • Formation of our Solar System • Evolution of Galaxies and Quasars • JCMT Legacy Surveys • Birth of Massive Galaxies at z~2 • Star Formation Processes • ALMA Pathfinder

  4. Canadian Astronomy Data Center • CADC’s Golden Age is ahead of us • Evolved from one data collection to many • Virtual Observatory spans the globe and the full range of classes of data • Future of Science Data Management lies in the multi-disciplinary Science Data Centre • Shares common low-level infrastructure • Shares elusive high-level functionalities • Visualization • Advanced analysis expertise • CADC is a unique Canadian resource

  5. Dataflow into CADC Space Flow > 1 Tbyte/week CANARIE is involved in improving the network from Hawaii

  6. Data delivered to science users Many users potentially at 1 Tbyte/week level

  7. Canadian Virtual Observatory / Observatoire Virtuel Canadien

  8. Distributed Data Query

  9. Distributed Data Query

  10. CADC is a leader

  11. Distributed Catalogue Query

  12. Orchestral performance: a meta-instrument for music Listener Conductor, score, auditorium, intelligence Bass, viola, cello, horns violins

  13. Astronomy IT infrastructure: A meta-instrument for science Science user Information technology infrastructure (hardware, software, intelligence) Scientific literature, Databases, Data Collections

  14. Virtual Observatory is based on open access to science data

  15. Canadian success in astronomy

  16. Open and Free Access Canadian Astronomy is first in the world in impact of science papers • 76921 citations to 4836 papers 1994-2004 CFRS Papers with Schade as first or a principal author • Five papers with 603 citations • 0.8% of all Canadian citations • 7.6 times average citation rate The papers combined CFHT spectroscopy with Hubble Space Telescope imaging These papers required free access to Hubble Space Telescope These papers required free access to HST data archive Canada has gained enormously from Open Access data policies

  17. Future Requirements Past • Get the data onto my hard drive Present • Data Centre is my hard drive • Applications read directly from CADC • Visualization • Data characterization and process configuration • Processing • Dataset sizes ~ 10’s of Terabytes

  18. Future Requirements Future • World is my hard drive/processor • Applications read directly from distributed data centres • View and characterize data/configure processing • Send data and configuration off to a remote processing node • Processing returns its results into a CADC database management/visualization/analysis environment • Dataset sizes ~ 100’s of Terabytes • Complexity of multi-wavelengths datasets is a challenge
