Parkes observations for project P574 semester 2021OCTS_13

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.

我们申请观测时长以对260颗脉冲星（pulsar）开展定期观测，旨在为利用费米卫星（Fermi satellite）探测与表征伽马射线脉冲星（gamma-ray pulsars）提供所需的精确星历表（ephemerides）。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，涵盖射电亮脉冲星（radio-loud pulsars）与射电宁静脉冲星（radio-quiet pulsars）两类；获取高精度脉冲轮廓（pulse profiles）；并对其高能量（相位分辨）光谱（high energy (phase-resolved) spectra）开展表征工作。在射电波段的观测还可支撑多项研究：通过探测脉冲星自转突变（glitch）并测定脉冲计时参数（pulse timing parameters），开展中子星（neutron star）与脉冲星辐射机制研究；通过测量并监测色散量（dispersion measures）、法拉第旋转量（Faraday rotation measures）与星际闪烁（scintillation），研究星际介质（Interstellar Medium，简称ISM）。截至目前，我们作为（共同）作者已参与本合作项目与P574数据集衍生的90余篇学术论文，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。
