VAST: An ASKAP Survey for Variables and Slow Transients

Along with Shami Chatterjee, I am leading the VAST project "An ASKAP Survey for Variables and Slow Transients". Our aim is to design a survey and software to run on the next generation radio telescope ASKAP, currently under construction in Western Australia.

Our science goals are broad, from the local to the cosmological, including flare stars, intermittent pulsars, X-ray binaries, magnetars, extreme scattering events, intra-day variables, radio supernovae and orphan afterglows of gamma ray bursts. For for information check out our public website or have a look at this article on theconversation. VAST was profiled in the 2010 October ASKAP Science Update.

Transients @ USyd

We have a growing group in radio transients at Sydney. Some of the people in our group are:

  • Bryan Gaensler, Australian Laureate Fellow
  • Paul Hancock, Curtin University
  • Martin Bell, CSIRO Astronomy and Space Science
  • Antonia Rowlinson, CSIRO Astronomy and Space Science
  • Davide Burlon, Postdoctoral Researcher
  • Cleo Loi, PhD student

I have lots of student projects in this area, either with an astronomy/astrophysics or IT/computer science focus. If you're interested, email me for more information.

AT20G: The Australia Telescope 20 GHz Survey

The AT20G is a recently completed blind survey of the entire Southern sky at 20 GHz, with follow-up observations of most objects at 5 and 8 GHz. We carried out this survey from 2004 to 2008 with the Australia Telescope Compact Array, resulting in a catalogue of 5890 sources above 40 mJy. Our final catalogue and papers are available on our website.

Early Career Research Showcase

The University of Sydney Early Career Research Showcase is now in its third year. It is a fun afternoon of short talks, aimed at a general audience, by early career research fellows from across the University. This is a chance to find out about the exciting research being done in the University, and to meet and talk to other researchers. For more information and to see programs from previous years, go to
