Description
The successor to the GaLactic and Extragalactic All-sky MWA (GLEAM) survey, GLEAM-eXtended uses the Phase II extended configuration of the MWA to survey the GLEAM sky at twice the resolution and up to an order of magnitude higher sensitivity. In 2020 we completed observations across the entire southern sky. The team is finalising the first data release, covering 2,000 square degrees, down to an RMS noise level of <1.5 mJy/beam in all Stokes parameters. We cover 72 — 231 MHz, illuminating the low-frequency behaviour of over 100,000 radio sources, and also perform searches for new polarised sources. Through creating the first data release we have learned valuable lessons on calibration and ionospheric behaviour, which we would like to share with the collaboration. The initial data release will be available for early science within the collaboration, pending publication later this year.
