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.
