Parkes observations for project P630 semester 2009APRS_19

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。本巡天将借助20厘米多波束系统与新型数字滤波器组阵列，生成拍字节级的全天数字观测记录，可供未来开展数据挖掘工作，并可用于搜寻相对论双星脉冲星、毫秒脉冲星、旋转射电暂现源（Rotating Radio Transients，RRATs）以及河外射电爆发。该巡天预计将发现数百颗全新的毫秒脉冲星与普通脉冲星，助力确定脉冲星周期的下限、验证相对论引力理论、搜寻暂现源，并为引力波探测提供可用脉冲星。当前所有硬件均已部署就绪，且我们已完成首次新脉冲星的发现，故申请本学期获得充足的观测时长分配。
