2dF Survey Data

The original 2dF observing system, upon which AAOmega is based, was responsible for two large survey programs, the data for which is hosted outside of the AAO:

  • The 2dF Galaxy Redshift Survey is a joint UK-Australian project, and was one of the main motivations behind the design of 2dF. The goal was to carry out a large redshift survey of 250,000 galaxies (selected from the APM Galaxy Catalog) to make a 3D map of the Southern Sky. A web mirror can be found at http://www.mso.anu.edu.au/2dFGRS.
    2dFGRS observations finished in April 2002, with over 220,000 galaxy redshifts obtained.

  • The 2dF QSO Redshift Survey was integrated with the galaxy survey and took spectra of 23,000 QSOs in parallel.
