Coriat et al. present the results of 2.1, 5.5, 9.0, 33 and 35 GHz
observations of the neutron star X-ray binary Circinus X-1, using the
Australia Telescope Compact Array. Advanced calibration and
de-convolution algorithms were used to overcome multiple issues due to
intrinsic variability of the source and direction-dependent
effects. The resulting centimetre and millimetre radio images show
spatially resolved jet structures from sub-arcsecond to arcminute
angular scales. The image above shows the large-scale ATCA radio
images of Cir X-1 at 2.1 GHz, showing the supernova remnant
surrounding Cir X-1. Full details are given in
the paper published in
Monthly Notices of the Royal Astronomical Society.
