Parkes observations for project P574 semester 2022APRS_05

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，以期获取精确的脉冲星计时星历，为费米（Fermi）卫星探测与表征伽马射线脉冲星提供必要支撑。本项目的核心科学目标包括：扩充已知伽马射线脉冲星的样本数量（涵盖射电亮与射电宁静两类）、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：通过探测自转突变与测定脉冲计时参数，研究中子星与脉冲星辐射机制；通过测量与监测色散量、法拉第旋转量及星际闪烁，研究星际介质（ISM）。截至目前，由本合作项目与P574数据集衍生的研究成果已发表超过95篇学术论文，其中4篇基于超宽波段（UWL）观测数据，我们均为这些论文的（共同）作者。相关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多位学生完成其博士学位论文。
