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

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

!! Delivers 2 Terabytes per week to users

!! 2500 distinct users

!! 87 countries

!! Serve all Canadian astronomy research universities

!! Largest astronomy data centre in the world (by data volume)

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

SDSS Archive

!! 10,000 sq deg (1/4 sky) !! 3D map of "local" Universe

(volume about 1030 cubic light yrs)

!! ~100 TB (FermiLab)
