Abstract
EMU is a wide-field radio continuum survey planned for the new Australian Square Kilometre Array Pathfinder (ASKAP) telescope. The primary goal of EMU is to make a deep (rms ~10 μJy/beam) radio continuum survey of the entire Southern sky at 1.3 GHz, extending as far North as +30° declination, with a resolution of 10 arcsec. EMU is expected to detect and catalogue about 70 million galaxies, including typical star-forming galaxies up to z ~ 1, powerful starbursts to even greater redshifts, and active galactic nuclei to the edge of the visible Universe. It will undoubtedly discover new classes of object. This paper defines the science goals and parameters of the survey, and describes the development of techniques necessary to maximise the science return from EMU.

The EMU team consists of over 180 members from 15 countries, all of whom are listed on http:askap. pbworks.com/TeamMembers. We thank them all for their significant contributions to the various stages of the EMU project. Of course, EMU will not be possible without ASKAP, and so we especially thank all the ASKAP staff, too numerous to name individually, who are actually designing and building the instrument on our behalf. We particularly thank the architects of the ASKAP science processing document: Tim Cornwell, Ben Humphreys, Emil Lenc, Max Voronkov, and Matt Whiting, for permission to use sections of that document. We also thank Lakshmi Saripalli for providing data on diffuse sources in ATLBS prior to publication, and Paul Nulsen for comments on a draft of this paper. The Centre for Allsky ASTROphysics (CAASTRO) is an Australian Research Council Centre of Excellence, funded by grant CE11E0090. ASKAP is sited on the Murchison Radio- Astronomy Observatory, which is jointly funded by the Commonwealth Government of Australia and the State Government of Western Australia. We acknowledge the Wajarri Yamatji people as the traditional owners of the Observatory site.Additional details
