Parkes observations for project P574 semester 2019OCTS_08

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.

本研究申请观测时长以定期观测260颗脉冲星，为利用费米卫星（Fermi satellite）探测与表征γ射线脉冲星（gamma-ray pulsars）提供所需的精确星历表。本项目的核心科学目标包括：扩充已知γ射线脉冲星的数量（涵盖射电亮与射电宁静两类），获取高精度脉冲轮廓，并表征其高能（相位分辨）能谱。在射电波段的观测还可支撑多项延伸研究：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、法拉第旋转量与星际闪烁，研究星际介质（Interstellar Medium, ISM）。截至目前，本团队依托本次合作与P574数据集已发表75篇论文，团队成员均为这些论文的（共同）作者。本数据集已助力波尔多、曼彻斯特、牛津、斯坦福与斯威本多所高校的学生完成博士学位论文。
