Results from the GaLactic and Extragalactic All-sky MWA Survey

Presented by Luke Hindson (University of Hertfordshire)

The Murchison Widefield Array has completed the most detailed survey of the southern sky, between 72 and 231 MHz, to date. The GaLactic and Extragalactic All-sky MWA (GLEAM) Survey has produced a robust catalogue of more than 300,000 extragalactic radio sources with a resolution of ~2.5 arcminutes and sensitivity of ~50 mJy for almost the entire sky south of +30 degrees with a flux scale accuracy of better than 10%. The GLEAM survey has also produced a map of the Milky Way between 260 < l < 340 allowing us to catalogue HII regions, SNRs, and study the diffuse Galactic background. I will present the challenges we have encountered in producing these catalogues, methods of source-extraction and characterisation, and discuss issues inherent to low frequency, wide field-of-view all-sky surveys such as GLEAM. I will present results from our extragalactic and Galactic catalogues, other scientific highlights, and upcoming science that has been made possible by GLEAM.
