Parkes observations for project P574 semester 2019APRS_03

We request time to observe 260 pulsars on a regular basis to provide the accurate ephemerides necessary for the detection and characterisation of gamma-ray pulsars with the Fermi satellite. The primary science goals are to increase the number of known gamma-ray pulsars (both radio loud and radio quiet), to determine accurate pulse profiles, and to characterise their high energy (phase-resolved) spectra. In the radio, the observations will also allow us to investigate: neutron stars and pulsar emission via detecting glitches and determining pulse timing parameters; and the ISM via measuring and monitoring dispersion measures, Faraday rotation measures, and scintillation. To date, we are (co-)authors on 75 papers arising from the collaboration and P574 data. The data have contributed to the PhD theses of students from Bordeaux, Manchester, Oxford, Stanford, and Swinburne.

我们申请观测机时，以定期对260颗脉冲星开展观测，从而获取精准的脉冲星星历表，为费米卫星（Fermi satellite）探测与表征伽马射线脉冲星提供必要支撑。本项目的核心科学目标如下：一是扩充已知伽马射线脉冲星的数量，涵盖射电亮与射电宁静两类；二是获取精准的脉冲轮廓；三是对其（相位分辨）高能光谱进行特性表征。在射电波段的观测还可支撑多项研究：通过探测脉冲星自转突变（glitch）并测定脉冲计时参数，开展中子星与脉冲星辐射机制研究；通过测量与监测色散量、法拉第旋转量及星际闪烁，研究星际介质（Interstellar Medium，简称ISM）。截至目前，我们作为合作团队（共同作者）已发表75篇基于本合作项目与P574数据集的学术论文。本数据集还助力了来自波尔多、曼彻斯特、牛津、斯坦福以及斯威本的学生完成其博士学位论文。
