The WiggleZ Dark Energy Survey was a large-scale galaxy redshift survey of bright emission-line galaxies with median redshift z = 0.6, carried out at the Anglo-Australian Telescope at Siding Spring, Australia between 2006 and 2011.
More than 200,000 redshifts were obtained, covering 1000 square degrees of equatorial sky in seven well-separated regions. WiggleZ galaxies were selected for observation using colour and magnitude cuts from a combination of optical and UV imaging. The optical imaging employed was from the SDSS in the Northern Galactic Pole and from the RCS2 survey in the Southern Galactic Pole, and UV imaging was provided by the GALEX satellite.
The WiggleZ data were used to produce some of the first high-redshift baryon acoustic oscillation measurements and growth of structure measurements, BAO measurements including density-field reconstruction, constraints on cosmological parameters and the properties of neutrinos, and many other scientific results.
