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.
