Working with John Magorrian, Dominic has been developing novel ways to study the formation of structure in disk galaxies. By taking a theoretical approach Dominic solves the Vlasov-Poisson equations, which describes the evolution of the disk, in order to understand how spiral arms are formed in such systems. Having developed the formalism, and the code to implement it, in his first year he now plans to apply it to a broad range of systems to gain physical insight into these awe inspiring systems. As he looks to the future, Dominic wants to make the connection between his theoretical models and the observations taken by the European Space Agency’s satellite, Gaia. Prior to starting his DPhil, Dominic completed an undergraduate degree in Physics at Keble College, Oxford and a Master’s degree in Mathematical and Theoretical Physics.
