The VIRMOS VLT Deep Survey

  • The Imaging survey and the Spectroscopic survey over sixteen square degrees of the sky in four separate fields.
The deep imaging is to obtain UBVRI over 16 deg^2 and K' imaging over selected areas, with the CFHT, ESO-NTT and ESO-2.2m.
The VLT VIMOS and NIRMOS will allow to measure redshifts from magnitude selected samples of galaxies picked from the imaging survey.
  • A sample of 100,000 redshifts for sources up to AB = 22.5.
Once a complete magnitude limited sample has been observed with a spectral resolution R~250
a sub-sample will be observed at R~2500-5000 to avoid any bias.
  • A sample of 50,000 redshifts for objects up to AB = 24
  • A sample of 1,000 redshifts for objects up to AB = 26
