Parkes observations for project P574 semester 2021APRS_02

We request time to observe 260 pulsars regularly in order to provide the accurate ephemerides necessary for the detection and characterisation of gamma-ray pulsars with the Fermi satellite. The main 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 over 90 papers arising from the collaboration and P574 data, including three which use UWL observations. The data have contributed to the PhD theses of students from Bordeaux, Manchester, Oxford, Stanford, and Swinburne.

我们申请对260颗脉冲星开展定期观测，以获取精确星历表，为利用费米卫星（Fermi satellite）探测并表征γ射线脉冲星提供必要支撑。本项目的核心科学目标包括：扩充已知γ射线脉冲星（含射电亮源与射电静默源）的数量；获取高精度脉冲轮廓；并表征其高能（相位分辨）能谱。在射电波段，本次观测还将助力我们开展多项研究：通过探测脉冲星自转突变与测定脉冲计时参数，探究中子星与脉冲星的辐射机制；通过测量并监测色散量、法拉第旋转量及射电闪烁，研究星际介质（ISM）。截至目前，我们作为合著者已基于本合作项目与P574数据集发表90余篇学术论文，其中3篇采用了UWL观测数据。上述数据集还支撑了来自波尔多大学、曼彻斯特大学、牛津大学、斯坦福大学及斯威本（Swinburne）的学生完成其博士学位论文。
