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.

16. 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

22. 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

23. 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
24. GB CADC archive stats per year
CADC: a week in the life

25. 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

26. SDSS Archive
!! 10,000 sq deg (1/4 sky)
!! 3D map of "local" Universe
(volume about 1030 cubic
light yrs)
!! ~100 TB (FermiLab)
