Testing pulsar emission models and general relativity at pico arcsecond resolution. A holographic technique has been pioneered that harnesses scattering in interstellar space to resolve the emission from pulsars at a resolution of 50 pico-arcseconds, six orders of magnitude finer than has been achieved by conventional radio astronomical interferometry. This project will directly measure the size of the emission regions in a set of pulsars, and hence resolve the 40-year old debate regarding the s ....Testing pulsar emission models and general relativity at pico arcsecond resolution.

The project will also apply the technique to binary pulsar systems to provide a new test of General Relativity.Read moreRead less

Summary
Modelling superfluid neutron stars. This project aims to construct realistic neutron star models, that will be used to interpret radio and x-ray data, but also to aid gravitational wave detection. These models will allow the study of matter at extreme densities in the stellar interior, well above nuclear density, thus making use of the most exciting physics laboratory in the cosmos.

Summary
Deep investigations of galaxies and pulsars. A new detector for the Parkes radio telescope will be made which will enable the use of new techniques for removing radio interference and, as a result, will allow researchers to detect fainter and more distant objects in the Universe than previously possible.
