Overview
- The mosaic merges GLEAM (2013–14) and GLEAM‑X (2018–20) surveys taken with the Murchison Widefield Array in Western Australia on Wajarri Yamaji Country.
- Compared with the 2019 GLEAM release, the new view delivers twice the resolution, ten times the sensitivity, and twice the sky coverage.
- ICRAR’s team catalogued about 98,000 radio sources across the Southern Galactic Plane, spanning pulsars, compact H II regions, planetary nebulae and distant galaxies.
- Processing spanned 18 months on Pawsey supercomputers, enabling clearer separation of supernova remnants from star‑forming regions and sharpening studies of pulsars.
- Researchers describe this as the first published low‑frequency image of the full Southern Galactic Plane, positioning it as a key resource ahead of SKA‑Low.
