  1. Canadian Survey Science Michael Balogh Department of Physics and Astronomy University of Waterloo

  2. Extragalactic astrophysics and the Survey • Galaxy formation/evolution is driven by observations • Need large statistical samples of very faint objects, over a wide wavelength range • Cosmic variance and environmental effects requires wide field

  3. What we missed • No direct Canadian participation in Sloan Digital Sky Survey • The dominant survey of the last 10 years • Fourth-most cited paper since 2000, behind only WMAP

  4. Future from the ground

  5. LSST • Will supersede most ground-based imaging • Not yet funded • Open to international participation • Cost would require supporting operations amounting to $40M at a pro-rated level • e.g. if Canadian users represent 5% of the total, cost would be $2M per year • Spectroscopic follow-up? Good basis for a dedicated wide-field 8-m spectrograph (WFMOS)

  6. Wide Field Space Imager • 2009: CSA Discipline Working Group recommended: • A dedicated, diffraction-limited, UV-optical 1m aperture telescope. HST resolution with 100x field of view. • Or: a UV/optical channel for a targeted IR imager such as JDEM.

  7. Wide Field Space Imager • Awarded contract to study possible payload contributions to an international Dark Energy Mission

  8. Summary • The next decade will see the beginning of several enormous surveys • CFHT will not be competitive in this era • There is currently no Canadian involvement in any of these surveys. • Options: • Buy into LSST • Provide WFMOS-like support to LSST • Contribute to a space DEM
