ESO-GOODS (Great Observatories Origins Deep Survey)

The Great Observatories Origins Deep Survey (GOODS) is a public, multiwavelength survey which originally covered two 150 square arcmin fields, centered around the HDF-N (Hubble Deep Field North) and the CDF-S (Chandra Deep Field South). It is a coordinated effort to combine the deepest survey data over the widest wavelength range (from X-ray through radio) from NASA’s Great Observatories (HST, Chandra, Sptizer), ESA’s XMM-Newton, and the largest ground-based observatories, namely ESO-VLT, Keck, Gemini in the optical/nearIR region, VLA in the radio, etc. Observations were designed to promote major advances in following primary science areas:

  • The mass assembly history of galaxies over the broadest accessible range of cosmic time
  • Census of energetic output from star formation and supermassive black holes
  • The formation of the Hubble sequence
  • Star formation history out to z∼7 and discovery of primordial galaxies
  • Supernovae at high redshifts and the cosmic expansion

The ESO-GOODS project consists of a number of observing campaigns in the CDFS field (in particular in the GOODS-South central region), primarily with the VLT, designed to complement the capabilities of HST prior to SM4. The VLT campaign was conducted under the programme "The Great Observatories Origins Deep Survey: ESO Public Observations of the SIRTF Legacy/HST Treasury/Chandra Deep Field South", with PI Catherine Cesarsky, over the periods P68-P77. As detailed in the Table below, this programme included:

As of Dec 09, all advanced data products have been publicly released via the ESO Archive.

In addition, panoramic, moderately deep imaging in UBVRI filters with WFI on the 2.2m La Silla Telescope, was carried out as part of the EIS project. Related data products were publicly released as part of the GaBoDS survey.

CDFS Spectroscopic Database

In addition to ESO-GOODS, many spectroscopic campaigns have been carried out in the CDFS area as part of VLT follow-up studies building on the GOODS multiwavelength data set. Over 4000 secure redshifts from 15 observing programs have been collected into a Spectroscopy Master Catalog and can be accessed via a search engine developed by ESO-ECF.

Data Policy

In the spirit of all Legacy Programs, data obtained with ESO facilities in direct support of the GOODS project were immediately made public worldwide. Science ready data products were prepared by the ESO-GOODS Team and publicly released into the ESO Archive in a progressive manner within 6-12 months from the conclusion of each observing run.
