Overview
- The image combines GLEAM and GLEAM‑X survey data from the Murchison Widefield Array on Wajarri Yamaji Country in Western Australia.
- Compared with the 2019 release, the new map delivers twice the resolution, ten times the sensitivity, and covers twice the sky area.
- ICRAR researchers catalogued about 98,000 radio sources across the southern Galactic Plane, including pulsars, planetary nebulae, compact HII regions, and distant galaxies.
- ICRAR reports more than 40,000 supercomputer hours over 18 months at the Pawsey Supercomputing Research Centre to assemble the image, while some outlets cite a disputed figure of 1 million CPU hours.
- The team describes this as the first published low‑frequency radio image of the entire Southern Galactic Plane, with SKA‑Low expected to surpass it in sensitivity and resolution once operational in the next decade.
