We report on a redshift survey of ∼ 4000 galaxies of B ≲ covering a 1500 square degree area of sky around the SGP region. This 1-in-3 sampled survey probes a contiguous volume of 4 × 106 Mpc3 to a depth of 300 h−1 Mpc. The survey has been compiled using the fibrelinked spectroscopy system, FLAIR, on the UK Schmidt Telescope and has produced high quality redshift maps giving a clear visual picture of structure in the universe as well as providing an excellent data base for a statistical analysis of galaxy clustering. Filamentary and sheet-like features are clearly discernible to the eye in the completed sections of the survey although the redshift two-point correlation function is consistent with zero on scales of r ≳ 10h−1 Mpc. The survey, which is now substantially complete, demonstrates the potential of the FLAIR spectroscopy system for extending this project to a medium-deep galaxy redshift survey of the whole of the southern sky on timescales which would remain competitive with other surveys under construction. |
