Large-scale structure from 2dFGRS

The 2dF Galaxy Redshift Survey was the first to observe more than 100,000 redshifts, making possible precise measurements of many aspects of galaxy clustering. The final database of more than 230,000 redshifts is now ready for public release, and this paper summarizes some of the key scientific results that it has yielded. Particular emphasis is given to the clustering as a function of galaxy type, showing that a consistent determination of the primordial matter power-spectrum shape can be made even though different classes of galaxy can display levels of bias that differ by a factor 2
