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.

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

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.
