About

We are looking for an enthusiastic and strongly motivated candidate to work on a computational project in Galactic dynamics and the modelling of massive black hole binaries as sources of gravitational waves. Low-frequency gravitational waves (GWs) form when binaries of massive black holes (MBHs) coalesce, providing a new window onto the physics of black hole growth and its connection to galaxy evolution. Mergers of the most massive MBHs are detectable by the Pulsar Timing Array (PTA)  while lower mass ones will be the main target of the Laser Space Interferometer (LISA). There are strong expectations that the PTA will detect the first low-frequency GWs from such mergers in the next few years.

In this project, the student will perform state-of-the-art simulations of mergers of massive, gas poor galaxies hosting central MBHs. Initial conditions will be sampled from cosmological merger trees. They will model the formation and evolution of binaries from pairing to coalescence to infer merger timescales for a range of MBH masses. Assuming different seed and growth models, they will study how MBHs grow and evolve over cosmic time.

The successful candidate will be trained in numerical simulations of galaxies and the dynamical modelling of supermassive black holes on High Performance Computing facilities. We will support development of research skills as well as a suite of transferable skills including leadership, communication and project management.

The astrophysics groups at Surrey and Milano Bicocca are diverse and inclusive and we welcome applications from candidates of any gender, ethnicity or background.
