Puppis A is the remnant of a supernova
explosion which occurred several thousand years ago and now appears as a shell
of ~1 deg diameter. This composite picture displays the radio
continuum emission (red) obtained by combining Parkes and broadband
ATCA observations, with a visible light (green)
background from the Digital Sky Survey. The multi-spectral capabilities of
the Compact Array Broadband Backend (CABB) made it possible to perform an
exhaustive spectral study, recently published by
Reynoso & Walsh
(2015, MNRAS, in press).
