A Deep Northern Census of Radio Pulsars: Initiating an Arecibo Multibeam Survey

随着明年国家天文和电离层中心阿雷西博天文台望远镜的一系列升级，该天文台准备对新的脉冲星进行大规模的深度调查。目前的估计是大约1000颗新的脉冲星将被发现。该系统将对速度最快的脉冲星和轨道周期少于几个小时的紧凑双星以及包括黑洞在内的所有可能的伴星具有很高的灵敏度。这对我们银河系的磁场和离子分布的详细建模，定义银河系的旋臂，以及致密双星的引力波研究都有意义。该项目将通过调查设计和试点观察、开发数据处理软件和调查射频干扰缓解技术，为调查奠定基础

AST-0206035PI CordesWith a number of upgrades coming to the Arecibo Observatory telescope of the National Astronomy and Ionospheric Center in the next year, the Observatory is poised to carry out a large-scale deep survey for new pulsars. Current estimates are that about 1000 new pulsars will be discovered. The system will have high sensitivity to the fastest pulsars and to compact binaries with orbital periods less than a few hours and with every possible kind of companion including black holes. There are implications for detailed modeling of the magnetic field and ionic distribution in our Galaxy, defining the Galaxy's spiral arms, and gravitational wave studies of compact binaries. This project will lay the groundwork for the survey through a survey design and pilot observations, developing data processing software, and investigating radio frequency interference mitigation techniques.***
