POSSUMs at the VLA
The ASKAP POSSUM Science Survey Team held a busy week at Socorro late last year. POSSUM -- the Polarisation Sky Survey of the Universe's Magnetism -- is one of the eight major surveys currently undertaking a pilot survey on ASKAP. POSSUM aims to catalog Faraday rotation measures (RMs) for around a million extragalactic radio sources, allowing (among other things) the 3D geometry of the Milky Way's magnetic field to be determined. During the week the team visited the Jansky Very Large Array, with the image above showing former CASS postdocs, Josh and Craig, on the surface of one of the twenty-seven 25m diameter dishes that make up the array.
