Parkes observations for project P574 semester 2018OCTS_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 find glitches, characterise timing noise, investigate dispersion and rotation measure variability, and enhance our knowledge of single pulse phenomenology. To date, we\r\nare (co-)authors on 70 papers arising from the collaboration and P574 data. The data have contributed to the PhD theses of students from Bordeaux, Stanford, Swinburne and Oxford.

本研究申请对260颗脉冲星开展定期观测，以获取精准的星历表（ephemerides），为利用费米卫星（Fermi satellite）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规模（涵盖射电亮与射电宁静两类）、获取高精度脉冲轮廓，并表征其高能（相位分辨）能谱。在射电波段开展的观测还将助力我们发现脉冲星自转突变（glitch）、表征计时噪声、研究色散与旋转量的变化特性，并深化对单脉冲现象学的认知。截至目前，本团队作为（共同）作者，已在由本合作项目与P574数据集衍生的70篇学术论文中署名。本数据集还支撑了来自波尔多大学、斯坦福大学、斯威本科技大学与牛津大学的多名学生完成其博士学位论文。
