Parkes observations for project P574 semester 2021OCTS_01

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.

我们申请观测时长以对260颗脉冲星开展定期观测，为利用费米（Fermi）卫星探测与表征伽马射线脉冲星提供所需的精准脉冲星星历表（ephemerides）。本项目的核心科学目标包括：扩充已知伽马射线脉冲星的数量（涵盖射电活跃与射电宁静两类）、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，本次观测还可支撑多项研究：通过探测脉冲星自转突变并测定脉冲计时参数，探究中子星与脉冲星辐射机制；通过测量与监测色散量、法拉第旋转量及射电闪烁，研究星际介质（ISM）。截至目前，基于本合作项目与P574数据集产出的学术论文中，我们作为（共同）作者参与了90余篇，其中3篇采用了UWL观测数据。本数据集还助力了来自波尔多、曼彻斯特、牛津、斯坦福及斯威本（Swinburne）的学生完成其博士学位论文。
