Abstract
The 6dF Galaxy Survey (6dFGS) is currently measuring the redshifts of
around 170 000 galaxies and the peculiar velocities of a 15 000-member subsample. It will be the largest redshift survey of the local universe and more
than an order of magnitude larger than any peculiar velocity survey to date.
When complete, it will cover essentially the entire southern sky around a mean
redshift of z = 0.05. Central to the survey is the Six-Degree Field (6dF) multi-
fibre spectrograph, an instrument able to record 150 simultaneous spectra over
the 5.7◦ -field of the UK Schmidt Telescope. Targets have been drawn from the
2MASS Extended Source Catalog (XSC) to include all galaxies brighter than
Ktot = 12.75, supplemented by 2MASS and SuperCOSMOS galaxies that complete the sample to limits of (H, J, rF , bJ ) = (13.05, 13.75, 15.6, 16.75). Here we describe the implementation of the survey and the procedures used to select sources and determine redshifts. We also describe early results utilising the First Data Release of ∼ 45 000 redshifts. There is an online database of 6dFGS data accessible from the 6dFGS web site (http://www.mso.anu.edu.au/6dFGS).
