Abstract
- We describe the `WiggleZ' spectroscopic survey of 280,000 star-forming galaxies selected from a combination of GALEX ultra-violet and SDSS + RCS2 optical imaging. The fundamental goal is a detection of the baryonic acoustic oscillations in galaxy clustering at high-redshift (0.5 < z < 1) and a precise measurement of the equation of state of dark energy from this purely geometric and robust method. The survey has already started on the 3.9m Anglo-Australian Telescope using the AAOmega spectrograph, and planned to complete during 2009. The WWW page for the survey can be found at http://astronomy.swin.edu.au/wigglez<br />To appear in the Proceedings of the Durham "Cosmic Frontiers" ASP conference eds. Metcalfe & Shanks, 8 pages, 5 figures, (Version 2: updated May 2007 with final analysis of data through to Nov 2006.)
