China has a large community of astronomers awaiting the construction of new telescopes to study pulsars.
When CSIRO pulsar researcher Dr George Hobbs described the high-quality data stored in the Parkes Observatory Pulsar Data Archive—which is openly available—it led to Australian pulsar data being the basis of collaboration between Chinese and Australian pulsar researchers. And they have already published several papers on what they have discovered. The archive is also serving as a major resource in an international search for gravitational waves.

Einstein’s general theory of relativity predicts them, and they could be scattered throughout the Universe. But so far, gravitational waves— ‘ripples’ in the fabric of space and time—have never been detected. Several Australian teams of astronomers are trying to catch the first signs of one.

CSIRO’s Dr John O’Sullivan, winner of the 2009 Prime Minister’s Prize for Science, is now working on the next generation of radio telescopes.
John’s latest efforts are directed towards the development of an innovative radio camera or ‘phased array feed’ with a uniquely wide field-of-view for the Australian SKA Pathfinder (ASKAP) radio telescope.
