PPT-Early Polarisation Science with ASKAP

Bryan Gaensler Tom Landecker Russ Taylor and the POSSUM team askaporg possum New Discovery Space with ASKAP12 Radio polarimetry a highly sensitive probe of density magnetic field and turbulence at all redshifts. ASKAP is a next-generation radio telescope incorporating novel receiver technologies and leading-edge ICT systems. It will be made up of  antennas, each  metres in diameter, working together a Polarisation. show an understanding that . polarisation. is a phenomenon . associated . with. . transverse. . waves.
