Welcome on z-COSMOS database @ LAM

zCOSMOS is an approved Large Program on the ESO VLT.
600 hours of observation are used to carry out a major redshift survey with the VIMOS spectrograph on the COSMOS field to yield spectra for:

  • approximately 28,000 galaxies at 0.2 < z < 1.2 selected to have I_AB < 22.5 at a sampling rate of 70%
  • approximately 12,000 galaxies at 1.2 < z < 3 with B_AB < 25 and chosen by two colour-selection criteria (B-Z) vs. (Z-K) and (U-B) vs. (V-R) at a sampling rate of 70%
