Parkes observations for project P574 semester 2022OCTS_09

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.

我们申请了观测时长，以定期监测260颗脉冲星，为费米（Fermi）卫星开展伽马射线脉冲星的探测与特性表征工作提供所需的精确脉冲星历表。本项目的核心科学目标包括：扩充已知伽马射线脉冲星（含射电亮脉冲星与射电静默脉冲星）的总量；获取高精度脉冲轮廓；并对其高能（相位分辨）能谱进行特性表征。射电波段的观测还将支持我们开展多项研究：通过探测脉冲星自转突变并测定脉冲计时参数，探究中子星与脉冲星的辐射机制；通过测量与监测色散量、法拉第旋转量及星际闪烁，研究星际介质（Interstellar Medium, ISM）。截至目前，我们作为（共同）作者参与了本合作项目与P574数据集产出的95余篇学术论文，其中4篇采用了UWL观测数据。该数据集还助力了来自波尔多、曼彻斯特、牛津、斯坦福及斯威本高校的学生完成其博士学位论文。
