COSMOS Observations: Spectroscopy

Major optical spectroscopy surveys for COSMOS are on-going:

  • zCOSMOS
    • 540 hr on the ESO VLT using the VIMOS spectrograph
    • Two part survey:
      1. 25,000 galaxies at 0.3 < z < 1.0 with IAB < 22.5
      2. 12,500 star-forming galaxies color selected for 1.4 < z < 2.5
    • Goals:
      • redshift survey to identify and characterize environment
      • accurate census galaxy populations
      • targetted AGN & X-ray sources
    • Team: S. Lilly (PI) + 25 others
  • Magellan COSMOS
    • 12 nights Spring 05 with IMACS spectrograph
    • 3000 galaxies sampling:
      1. passively-evolving galaxies at 1.4 < z < 2.5
      2. high redshift galaxies and AGN
    • Team PIs: C. Impey (Az), P. McCarthy (Carnegie), M. Elvis (CfA) and J. Huchra (CfA) + others
  • Other Spectroscopy
    • Keck DEIMOS and LRIS:
      3 nights - Evolution of the Fundamental Plane , N. Scoville (PI) + 5 others
    • Galileo DOLORES and NICS:
      5 nights - Opt/IR Spect. of XBONG and EROs AGN , A. Comastri (PI) + 10 others
