Parkes observations for project P574 semester 2023APRS_01

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.

我们申请了定期观测260颗脉冲星的观测机时，以获取精确的星历表（ephemerides），为利用费米卫星（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包括：一是扩充已知伽马射线脉冲星的数量（涵盖射电亮脉冲星与射电宁静脉冲星两类）；二是获取高精度的脉冲轮廓（pulse profiles）；三是表征其高能（相位分辨）能谱。本次射电观测还可支撑多项拓展研究：通过探测脉冲星自转突变（glitches）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 measure）、法拉第旋转量（Faraday rotation measure）以及星际闪烁（scintillation），研究星际介质（Interstellar Medium，简称ISM）。截至目前，依托本合作项目与P574数据集产出的学术论文中，我们作为（共同）作者的已有95余篇，其中4篇使用了UWL观测数据。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（Swinburne）院校的学生完成博士学位论文。
