Chris Pritchett
Professor, Physics and Astronomy,
University of Victoria

Presented at the Cybera/CANARIE National Summit 2009, as part of the session "Research Transformed by Cyberinfrastructure." This panel featured researchers who have seen their work transformed through cyberinfrastructure – ie. collaborations made possible, mountains of data rendered intelligible, remote instrumentation accessed.

  • Manchester Guardian Oct 6 4
  • 5
  • Cyberinfrastructure in the 80's 6
  • Telescope vs. CCD total area in 3m+ telescopes [m2] total CCD area [Megapix]
  • Cyberinfrastructure Transforms Research: Supernovae and Cosmology 9
  • Expansion of the Universe Feb 9th, 1948 Hubble 1929 10
  • Fate of the Universe past future low density ? size of Universe high density big bang now time 11
  • Supernovae 12
  • Brightness and "redshift" 13
  • MegaCam at the Canada- France-Hawaii Telescope ~ 0.5 Gigapixels 14
  • The Universe - a dark energy 70% dark matter 25% normal matter 5% 15
  • Supernova Survey !! Images taken at CFHT in Hawaii !! Find supernovae within ~12 hr !! software in Victoria !! database in Toronto !! Obtain spectra on 8m class telescopes in Hawaii and Chile !! within 1-2 nights of imaging data 16
  • CFHT 17
  • 18
  • ~100 GB/night 19
  • Cyberinfrastructure Transforms Research: Archiving and Data Mining 20
  • Changing Sociology of Astronomy 1600's 1970's 21 2001
  • Changing Sociology of Astronomy !! Science Teams 25 years ago: !! Individuals or groups of 2-3 people !! Allocations of a few nights of telescope time/year !! Small data collections for each project !! Science Teams Today: !! groups of dozens of people all over the world !! Allocations of 10%-30% of ALL telescope time is not uncommon !! Large data collections for each project !! Why the change? !! Better, more comprehensive science from large surveys 22
  • Canadian Astronomy Data Centre HST !! Delivers 2 Terabytes FUSE per week to users !! 2500 distinct users MOST !! 87 countries CFHT !! Serve all Canadian astronomy research Gemini universities !! Largest astronomy data BLAST centre in the world (by data volume) JCMT CGPS MACHO
  • GB CADC archive stats per year CADC: a week in the life 24
  • Changing Role of CADC !! CADC 25 years ago: !! Archived data !! Made data accessible !! Today !! Design data management processes and systems in collaboration with observatories and Science Teams !! Implement and Operate these data management systems !! Why the change? !! Individual Science Teams cannot handle the processing and storage requirements for very large survey projects 25
  • SDSS Archive !! 10,000 sq deg (1/4 sky) !! 3D map of "local" Universe (volume about 1030 cubic light yrs) !! ~100 TB (FermiLab) 26
