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.***

AST-0206035PI望远镜随着国家天文和电离层中心阿雷西博天文台望远镜明年将进行一些升级，天文台准备对新的脉冲星进行大规模的深度调查。目前的估计是将发现大约1000颗新的脉冲星。该系统将对最快的脉冲星、轨道周期小于几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高度的灵敏度。这对我们银河系中磁场和离子分布的详细建模、定义银河系的旋臂以及对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测、开发数据处理软件和调查无线电频率干扰缓解技术为调查奠定基础。*
