I’m Toby Brown, an astronomy PhD student at ICRAR.

My research focuses on the role of gas in the complex mash-up of physical processes that drive galaxy evolution.

I also talk about science on the side.

I specialise in the analysis of large scale multi-wavelength samples of galaxies. In particular, I want to understand how the neutral atomic hydrogen (HI) gas reservoirs of galaxies are linked to star formation, structural and environmental properties of galaxies. I use 25,000 galaxies –  the largest sample of HI data to date – and the powerful spectral stacking technique to provide the very first large-scale, statistical census of cold gas and environment for galaxies in the local Universe.

While my work is primarily observational, I maintain strong links with theory, having collaborated closely with leaders in the field to constrain the HI content of galaxies in cosmological models of galaxy formation.

Due to the statistical nature and methods of my work, I spend much of my time writing, developing and optimising bespoke software for data visualisation and analysis.

Science Communication

I am also a passionate science communicator and outreach enthusiast. When I’m not peering at the Universe I spend my time talking about it through radio, writing and award winning public talks!
