Parkes observations for project P574 semester 2021APRS_05

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.

本研究申请对260颗脉冲星开展定期观测，以获取精准的脉冲星星历表，为费米卫星（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：扩充已知伽马射线脉冲星（涵盖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。在射电波段开展的观测还将支持多项研究：通过探测脉冲星自转突变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、法拉第旋转量以及射电闪烁现象，研究星际介质（Interstellar Medium，ISM）。截至目前，本团队作为作者（含共同作者）已在依托本合作项目与P574数据集产出的90余篇学术论文中署名，其中3篇利用了UWL观测数据。该数据集还助力波尔多大学、曼彻斯特大学、牛津大学、斯坦福大学以及斯威本科技大学的多名学生完成其博士学位论文。
