Parkes observations for project P574 semester 2021APRS_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.

我们申请定期观测260颗脉冲星的观测时长，以获取精准的脉冲星历表，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的数量（涵盖射电明亮型与射电宁静型两类）、获取高精度脉冲轮廓，以及表征其高能（相位分辨）能谱。射电波段的观测还可支撑我们开展如下研究：通过探测自转突变（glitch）并测定脉冲计时参数，研究中子星与脉冲星的辐射机制；通过测量并监测色散量、法拉第旋转量与星际闪烁，研究星际介质（Interstellar Medium, ISM）。截至目前，依托本合作项目与P574数据集衍生出的学术论文中，我们作为（共同）作者的成果已逾90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、斯坦福以及斯威本的学生完成其博士学位论文。
