ASKAP linear polarisation image of Fornax A
This ASKAP image was made from a single beam observation of Fornax A (NGC 1316), one of the brightest radio galaxies. Yesterday's ADAP showed the total intensity image: today's shows the intensity of linearly polarised emission. With X-Y phase alignment (where X and Y are the two orthogonal polarisations detected by the PAF) now performed automatically at beam formation using the ASKAP on-dish calibration system, all ASKAP data provide useful polarisation information. This image was made by Craig Anderson and compares very well to published data from the Very Large Array. More details are given in last month's ASKAP Commissioning Update.
