Parkes observations for project P574 semester 2023OCTS_02

We request time to observe 260 pulsars on a regular basis 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 95 papers arising from the collaboration and P574 data, including four which use UWL observations. The data have contributed to the PhD theses of students from Bordeaux, Manchester, Oxford, Stanford, and Swinburne.本研究申请对260颗脉冲星开展常规观测，以获取精准的星历表(ephemerides)，为利用费米卫星(Fermi)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射线脉冲星的数量（涵盖射电亮与射电宁静两类）、获取高精度脉冲轮廓，以及表征其高能（相位分辨）能谱。在射电波段，本次观测还将支持我们开展如下研究：通过探测自转突变(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(dispersion measures)、法拉第旋转量(Faraday rotation measures)以及星际闪烁(scintillation)，研究星际介质(ISM)。截至目前，本团队作为（共同）作者，在本合作项目与P574数据衍生出的95余篇学术论文中署名，其中4篇采用了UWL观测数据。本项目数据还助力了来自波尔多、曼彻斯特、牛津、斯坦福以及斯威本等院校的学生完成博士学位论文。
