The DEEP survey is a two-phased project using the Keck telescopes to study the distant Universe.

  • Phase 1 used the LRIS spectrograph to study a sample of ~1000 galaxies to a limit of I=24.5.
  • Phase 2 of the DEEP project is using the new DEIMOS spectrograph to obtain spectra of ~50,000 faint galaxies with redshifts z > 0.7.
