Polarised radio sources in the XXL-South field
by Eyles et al.
Eyles et al. have investigated the properties of the polarised radio population in the central 6.5 square degrees of the XXL-South X-ray survey field. The observations were made at 2.1 GHz using the Australia Telescope Compact Array (ATCA) as a mosaic with 81 pointings and a synthesised beam of FWHM 5.2 arcseconds. A total of 39 polarised sources, involving 50 polarised source components, were found above a polarised flux density limit of 0.2 mJy at 1.3 GHz. The images above are examples images. The heat map indicates total intensity in Jy/beam, azure contours indicate polarised intensity at 0.5, 1 and 2 mJy, and red crosses indicate the centre of each source component as identified by fits to the total intensity. In these multi-component sources, each component is also labelled. The FWHM of the synthesised beam is shown in the bottom right corner of each plot. More details are given in the paper by Eyles et al, to be published in Astronomy & Astrophysics.
