Note:The Australia Telescope 20 GHz (AT20G) Survey is a blind survey of the whole Southern sky at 20 GHz (with follow-up observations at 5 and 8 GHz) carried out with the Australia Telescope Compact Array (ATCA) from 2004 to 2007. To date, it has completed the scan of the full Southern sky, detecting, down to a 50 mJy flux limit, more than 4400 sources below declination -15deg and expecting 1500 in the declination range -15deg dec <0deg for which the analysis is still on-going. Authors have performed near simultaneous observations of total intensity and polarization of the sources at 20, 8 and 5 GHz.
2008MNRAS.384..775M is the first ref. with AT20G objects.
2010MNRAS.402.2403M is the full source catalogue (version 1.0).
