We have recently published the 300-MHz component of the GaLactic and Extragalactic All-sky MWA survey (GLEAM-300), with 338k sources covering the sky up to declination +40 deg, with ~120" angular resolution and ~9 mJy/beam noise. The description paper is published via PASA: doi.org/10.1017/pasa....

Delighted to have this paper accepted. It was a fun collaboration with FRESCO/MIGHTEE. The radio luminosity/SFR correlation still holds at z~1.3! And we also showed that the scatter in the relation could be partly due to synchrotron emission being a delayed tracer of star formation. lnkd.in/gE5t3JBs

Another new paper: did you know that humans are much better at finding super-massive black holes than humans? Ivy Wong presents the first data release of 0.1 million classified radio galaxies each examined multiple times by citizen scientists.

Dead galaxies do the talking! A novel analysis of dead and dying radio galaxies has allowed a former student, Ben Quici, to determine how long the radio galaxy population lives for and how brightly they shine. This has big implications for models of the evolution of radio galaxies.

Devasting to see all the damage caused by the fires in LA. This has hit several communities hard with many friends and former astronomy losing their homes. If you can help please do so here: securelb.imodules.com/s/1709/devas...

Low-Frequency Turnover Star Forming Galaxies I: Radio Continuum Observations and Global Properties
The broad-band radio spectral energy distribution (SED) of star-forming galaxies (SFGs) contains a wealth of complex physics. We aim to determine the physical emission and loss processes causing radio...
