The GaLactic and Extragalactic All-sky MWA (GLEAM) survey shows the Universe in “radio colour”. To bring this vision to the public, I have built the “GLEAMoscope”, using the Chromoscope framework, which allows you to compare GLEAM with other wavelengths. Visit the GLEAMoscope page to play in full-screen, or embed it yourself on your own page using this code:

Working with an Android developer, I’ve also created the GLEAM “app” for Android phones. You can download it from the Google Play store, or follow this link. It will also appear in 3D with Google Cardboard: I’ve synthesised the parallax of the various objects to indicate what is closer and further away (although of course, this is not to scale!).


GLEAM is an excellent survey, but it does have one critical flaw: it has very low resolution. The Alternative Data Release 1 of the TIFR GMRT Sky Survey (TGSS-ADR1) provides a higher-resolution view of the sky, but is on a different flux density scale to GLEAM. This arXiv paper explores the differences and demonstrates a rescaled version of TGSS-ADR1 to match the GLEAM flux density scale. You can obtain the resulting catalogue here.



To correct for the warping effect of the ionosphere on radio astronomy images, I co-wrote the fits_warp algorithm with Dr Paul Hancock. You can download the algorithm from github, or read more about it in our paper in Astronomy & Computing.
