Parkes observations for project P574 semester 2020OCTS_02

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 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 find glitches, characterise timing noise, investigate dispersion and rotation measure variability, and enhance our knowledge of single pulse phenomenology. To date, we are (co-)authors on over 80 papers arising from the collaboration and P574 data. The data have contributed to the PhD theses of students from Bordeaux, Oxford, Manchester, Stanford, and Swinburne.

我们申请定期观测260颗脉冲星，以获取精准的星历表，为费米（Fermi）卫星探测并表征γ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γ射线脉冲星（涵盖射电亮与射电宁静两类）的总量，测定高精度脉冲轮廓，并表征其高能（相位分辨）能谱。在射电波段开展的观测还将支持我们完成多项研究：发现脉冲星自转突变、表征计时噪声、探究色散与旋转量的变化特性，以及深化对单脉冲现象学的认知。截至目前，源自本合作项目及P574数据集的论文中，我们作为共同作者的成果已逾80篇。该数据集还助力了来自波尔多、牛津、曼彻斯特、斯坦福与斯威本科技大学的学生完成其博士学位论文。
