Millisecond pulsar timing currently provides the most sensitive method of detecting long-period gravitational waves which permeate the Universe. Parkes leads the world in the discovery and timing of millisecond pulsars. This has motivated the development of three new advanced instruments including a cyrogenic dual-band receiver, a very wide-band correlator and a baseband recorder with an in-built supercomputer. We aim to exploit these new technologies to systematically study the pulsar population. We will establish a timing array which can detect gravitational waves, enable GLAST to identify over 100 gamma-ray pulsars and study the pulsar emission mechanism at sub-microsecond time resolution.

毫秒脉冲星计时目前提供了最灵敏的方法来探测渗透宇宙的长周期引力波。帕克斯在发现毫秒双星和计时方面处于世界领先地位。这推动了三种新的先进仪器的开发，包括低温双波段接收器，甚宽带相关器和内置超级计算机的基带记录器。我们的目标是利用这些新技术来系统地研究脉冲星种群。我们将建立一个可以探测引力波的定时阵列，使GLAST能够识别100多个伽马射线源，并在亚微秒时间分辨率上研究脉冲星的发射机制。
