Overview

I am an astronomer who writes about astronomy. In my day job, I carry out research into the origin and evolution of galaxies, using telescopes all around the world and in space. After originally doing a PhD in radio astronomy, I have spent much of my career using telescopes that observe in the submillimetre waveband, the last of the electromagnetic wavebands to be opened up for astronomy (the 'final frontier'). In my other life, writing, I try not just to describe the discoveries we have made about the universe, cool those there are, but the messy human stories of how these discoveries were made.

Research Interests

Galaxies are assemblies of stars that range in size from the tiny dwarf galaxies attached to our galaxy, which contain only a few thousand stars, to the giant galaxies at the centres of rich clusters, which sometimes contain over one trillion stars. My main research goals are to understand these fascinating objects, which are made up of stars, gas and dark matter - in particular how they were formed in the first place and how they and the universe have changed together during the 14 billion years since the big bang. Much of the light from these objects, in particular during the first billion years after their birth, is hidden by cosmic dust, tiny solid particles in interstellar space. In my research I therefore make a lot of use of submillimetre telescopes, such as the Herschel Space Observatory and the Atacama Large Millimetre Array, which effectively allow us to peer through the dust. I am also interested in many other research fields in astronomy, ranging from ones such as the measurement of the universe's basic properties (the cosmic parameters) in which I am actively involved to ones such as exoplanets and astrobiology in which I am not an active participant but an enthralled onlooker.

Current Research Projects

  • I was the co-leader of the largest Herschel survey of the extragalactic universe, the Herschel ATLAS. Although we have now released our images and catalogues to the worldwide astronomy community, my research team is still working on many projects with this magnificent dataset, include a project to find all the galaxies producing the submm emission in the hundreds of thousands of sources detected in our survey.
  • I am using ALMA to study the gravitationally-lensed sources discovered with Herschel, with the aims of using the magnification provided by the lenses to study the gas and the stars in these galaxy-building events.
  • The first submillimetre telescope was commissioned in 1987, but after 30 years of submillimetre astronomy we still do not have a submillimetre image of the nearest big spiral galaxy, the Andromeda Galaxy, because of the difficulty of getting an image of an object that covers such a large area of sky. My research team is leading an international project to produce the first high-fidelity submillimetre images of Andromeda, which will allow us to study the dust and the stars in a galaxy other than our own with unprecedented resolution.
  • With Herschel we could routinely detect galaxies out to a redshift of six, less than one billon years after the big bang. We aim to go even further back in time with MUSCAT, a new millimetre telescope that has been built by the Cardiff Astronomy Instrumentation Group. Once the pandemic is over, this camera will be shipped to the Large Millimetre Telescope in Mexico where we will use it to detect the first generation of galaxies, only a few hundred million years after the big bang, as well as protoclusters, the first large-scale assemblies of galaxies that will eventually, after ten billion years or so, become the rich clusters of galaxies we see around us today.
