Parkes observations for project P574 semester 2019APRS_08

We request time to observe 260 pulsars on a regular basis to provide the accurate ephemerides necessary for the detection and characterisation of gamma-ray pulsars with the Fermi satellite. The primary 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 75 papers arising from the collaboration and P574 data. 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颗脉冲星的时间，以提供精确的星历表（ephemerides）——这是利用费米卫星（Fermi satellite）探测和表征伽马射线脉冲星所需的核心数据。主要科学目标包括：增加已知伽马射线脉冲星（含射电亮源与射电暗源）的数量、测定精确的脉冲轮廓，以及表征其高能（相位分辨）谱。在射电波段，这些观测还将助力以下研究：通过探测 glitch 现象与测定脉冲计时参数，揭示中子星及脉冲星的辐射机制；通过测量与监测色散量、法拉第旋转量及闪烁效应，研究星际介质（ISM）。截至目前，我们作为（共同）作者参与发表了75篇基于该合作项目及P574数据的论文，这些数据已为波尔多、曼彻斯特、牛津、斯坦福及斯威本大学学生的博士论文提供了重要支撑。
