Parkes observations for project P574 semester 2022OCTS_07

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.

我们申请定期观测260颗脉冲星，旨在为费米卫星（Fermi satellite）探测和表征伽马射线脉冲星（gamma-ray pulsars）提供所需的精确星历表（ephemerides）。主要科学目标包括增加已知伽马射线脉冲星（含射电明亮与射电宁静两类）的数量、确定精确的脉冲轮廓、以及表征其高能（相位分辨，phase-resolved）谱。在射电波段，这些观测还将支持以下研究：通过探测星震（glitch）和确定脉冲计时参数，探究中子星与脉冲星的辐射机制；通过测量和监测色散量、法拉第旋转量及闪烁现象，研究星际介质（Interstellar Medium, ISM）。截至目前，我们作为（共同）作者参与发表了95余篇基于该合作项目及P574数据的论文，其中4篇采用了UWL观测数据。这些数据已助力Bordeaux、Manchester、Oxford、Stanford及Swinburne等高校学生完成博士学位论文。
