Dr. Ewan Barr

I am part of a team working on the revival of the SKA Molonglo Pathfinder (SKAMP) project. The Molonglo Observatory Synthesis Telescope (MOST) is Australia's largest radio telescope and has the potential to be a world class radio astronomy facility. However, past difficulties have led to the telescope falling out of use. Together with collaborators at Sydney University and CSIRO, we are developing a state-of-the-art backend system which will allow us to perform high-resolution, wide-FOV observations with MOST. The wide FOV will make MOST a fantastic instrument for detecting short-duration, non-repeating radio bursts like the famed "Lorimer Burst" (bursts which have now been shown to extra-Galactic in origin, Thornton et al. 2013). By observing for 24 hours a day, MOST will be capable of rapidly characterising these bursts, giving us new insight into their origins. MOST will also be capable of the continual monitoring of many pulsars (at the same time as searching for transients) and will have the ability to perform timing analysis on all pulsars in the FOV simultaneously. Such a high density of observations will provide a wealth of information on the nature of pulsar mode switching, nulling, intermittency and glitching as we expect to be able to observe >500 pulsars each day. Beyond SKAMP, my research interests focus around pulsar searching (with particular focus on the development of GPU based search algorithms) and timing. I am also involved in both the HTRU and HTRU-North pulsar surveys and am a member of the Parkes Pulsar Timing Array collaboration.
