Parkes observations for project P630 semester 2009APRS_05

We propose to carry out the most ambitious and comprehensive all-sky survey for pulsars and transient sources to date. Using the 20cm multibeam and a new digital filterbank array this survey will create a petabyte digital record of the sky that can be data mined in the future and used to search for relativistic binary and millisecond pulsars, RRATs, and extragalactic radio bursts. The survey should discover 100s of new millisecond and normal pulsars and help define the lower limit to pulsar periods, test theories of relativistic gravity, find transients and provide pulsars for gravitational wave detection. With all the hardware in place, and our first new pulsar discovery made, we request a substantial time allocation this semester.本研究提出开展迄今为止规模最宏大、覆盖最全面的全天域脉冲星与暂现源巡天项目。借助20厘米多波束系统 (20cm multibeam) 与新型数字滤波器组阵列 (digital filterbank array)，本巡天将生成拍字节 (petabyte) 级的全天数字记录，该记录可用于未来的数据挖掘，并用于搜寻相对论双星毫秒脉冲星、旋转射电暂现源 (RRATs) 以及河外射电暴。本次巡天将发现数百颗全新的毫秒脉冲星与常规脉冲星，助力确定脉冲星周期下限、检验相对论引力理论、探测暂现源，并为引力波 (gravitational wave) 探测提供可用脉冲星。目前所有硬件均已部署到位，且我们已成功完成首次新脉冲星发现，故本研究申请本学期分配大量观测时长。
