David John Williamson presents Big computers and little galaxies at the Winchester Science Centres monthly talk.
Abstract: What exactly does a “supercomputer” look like these days? How do astronomers use them, and what kind of results do they get? Using results from dwarf galaxies simulations performed at Southampton University, David will answer these questions and explain what they tell us about these vulnerable little galaxies, and the local universe in general.
The Lecturer: Born in New Zealand, David Williamson completed an MSc in Condensed Matter Physics at Victoria University of Wellington before pursuing his true passion of astronomy and undertaking a PhD in Computational Astrophysics at Saint Mary’s University in Halifax, Canada. After three years as a postdoctoral researcher at Université Laval in Québec City, he has been working as a postdoctoral researcher at Southampton University since 2016, developing simulations of active galactic nuclei and dwarf galaxies.
