GLEAM-300
Listed in IVOA Registry (Virtual Observatory)
We present a wide-field radio survey at 300MHz covering the sky from -90 degrees to +40 degrees in declination using the Murchison Widefield Array (MWA).
Description
This 300-MHz survey follows the Galactic and Extragalactic All-sky MWA (GLEAM) survey, and provides an additional comparatively high-frequency data point to existing multi-frequency (72-231MHz) data. With this data release we provide mosaic images and a catalogue of compact source components.
We use two-minute snapshot observations covering 2015 to 2016, combining overlapping two-minute snapshot images to provide full-sensitivity mosaic images with a median root-mean-square noise of 9.1^+5.5^_-2.8_mJy/beam and median angular resolution of 128.8"x112.5", with some position-dependent variation. We find a total of 338080 unique Gaussian components across the mosaic images. The survey is the first at 300MHz from the MWA covering the whole Southern Hemisphere.

It provides a unique spectral data point that complements the existing GLEAM survey and the ongoing GLEAM-eXtended survey, and points toward results from the upcoming SKA-Low surveys.
