Article Synopsis
  • Galaxies group together through gravity to form clusters, interconnected by a web-like structure, which is suggested to emit radio waves due to strong shocks.
  • Observations indicate that Fermi-type acceleration occurs in these shocks around cosmic filaments and low-mass clusters.
  • The detection of polarized synchrotron emission supports the idea that strong shock waves organize local magnetic fields in and around these cosmic structures.

We describe a new low-frequency wideband radio survey of the southern sky. Observations covering 72-231MHz and Declinations south of +30° have been performed with the Murchison Widefield Array "extended" Phase I I configuration over 2018-2020 and will be processed to form data products including continuum and polarisation images and mosaics, multi-frequency catalogues, transient search data, and ionospheric measurements. From a pilot field described in this work, we publish an initial data release covering 1,447 deg over 4 h≤ RA≤ 13 h, -32.
