High-resolution shock-capturing (HRSC) methods for elastic matter in general relativity
Carsten Gundlach, Ian Hawke, Stephanie Erickson (Investigators)
We are designing HRSC methods for numerical simulation of elastic matter coupled to general relativity and later magnetic fields, with the ultimate aim of simulating old neutron stars, which have elastic crusts.
Lattice Holographic Cosmology
Andreas Juttner (Investigator), Matthew Mostert
This project will aim to develop new theoretical field methods and massively parallel computational algorithms to be utilised on both new computational architectures (e.g. Intel Xeon Phi) and existing high performance computers (HPCs).
The ultimate goal is to make predictions for the power spectrum and non-gaussianties of the CMB which would then be falsifiable by comparison to the Planck and WMAP data.

Multiscale modelling of neutron star oceans
Ian Hawke (Investigator), Alice Harpole
Type I X-ray bursts are explosions which occur on the surface of some
neutron stars. It is believed that the burning begins in a localised spot in the ocean of the
star before spreading across the entire surface. By gaining a better understanding of X-ray
bursts, it is hoped that tighter limits can be determined for other neutron star properties
such as the radius and magnetic field strength.
Multiscale Relativistic Simulations
Ian Hawke (Investigator), Alex Wright
There has been recent success in experiments, such as LIGO, in detecting the mergers of celestial objects via the gravitational waves they emit. By implementing numerical methods, we aim to speed up the numerical simulations of these events but up to two orders of magnitudes, and study binary inspirals in greater detail and over much larger timespans.
Multiscale Relativistic Simulations
There has been recent success in experiments, such as LIGO, in detecting the mergers of celestial objects via the gravitational waves they emit. I will use numerical methods to simulate the inspiral of a black hole/neutron star binary system.
Numerical Elastic Neutron Stars
Ian Hawke, Ian Jones (Investigators), Andrew Penner
We study the astrophysical effects of the crust on a neutron star using an elasto-hydrodynamic model.
Relativistic multifluids
Ian Hawke (Investigator)
Multiphase flow is a central model in fluid dynamics. Its extension to relativity is crucial for tackling many astrophysics problems, and has fascinating mathematical features.
Self-Force and Black Hole Inspirals
Sam Dolan (Investigator)
We use IRIDIS to compute the self-force acting on a solar-mass black hole orbiting a supermassive black hole.
