Radio pulsars are the collapsed cores of once-massive stars that are renowned for their exceptional rotational stability. Ever since their discovery Australia has played a prominent role in the discovery and monitoring of these enigmatic sources. The timing and discovery of millisecond pulsars is an area where Australia is a world leader. This programme will use a powerful new instrument on the Parkes radio telescope to search for the minute influence of gravitational waves from supermassive black hole binaries on the millisecond pulsars.

射电脉冲星是曾经的大质量恒星的坍塌核心，这些恒星以其非凡的旋转稳定性而闻名。自从它们被发现以来，澳大利亚在发现和监测这些神秘来源方面发挥了突出的作用。毫秒脉冲星的计时和发现是澳大利亚处于世界领先地位的一个领域。该计划将使用帕克斯射电望远镜上的一台强大的新仪器来搜索来自超大质量黑洞双星的引力波对毫秒脉冲星的微小影响。
