Parkes observations for project P574 semester 2022APRS_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.

我们申请观测时长以定期观测260颗脉冲星，从而为利用费米卫星（Fermi Satellite）探测与表征伽马射线脉冲星提供所需的精确星历表。本项目的主要科学目标包括：增加已知伽马射线脉冲星（涵盖射电亮与射电宁静两类）的数量；获取精确的脉冲轮廓；以及表征其高能（相位分辨）能谱。在射电波段的观测还将支持我们开展多项研究：通过探测脉冲星突跳并测定脉冲计时参数，研究中子星与脉冲星辐射机制；通过测量与监测色散量、法拉第旋转量以及星际闪烁，研究星际介质（Interstellar Medium，ISM）。截至目前，基于本合作项目与P574数据产生的论文中，我们作为（共同）作者参与了超过95篇，其中4篇使用了UWL观测数据。这些数据还助力了来自波尔多、曼彻斯特、牛津、斯坦福以及斯威本院校的学生完成其博士学位论文。
