The mid-band Rapid ASKAP Continuum Survey
by Duchesne et al.
Duchesne et al. have recently published the Rapid ASKAP Continuum Survey (RACS) at 1367.5 MHz, "RACS-mid", which covers the whole sky south of a declination of +49 degrees. The image above is an example of a RACS-mid image, featuring extended radio galaxies in the galaxy cluster Abell 754 along with point sources to provide a qualitative idea of the image fidelity for a representative extra-Galactic field. Abell 754 is a galaxy cluster formed from the collision of two smaller clusters. This merger began a relatively recent ~300 million years ago and the system is still quite disturbed.
