Parkes observations for project P574 semester 2015APRS_BPSR_09

We request time to observe 230 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 48 papers arising from the collaboration and P574 data. The data have contributed to the PhD theses of students from the Bordeaux group and Stanford and are in remain in active use (detailed within).

本研究申请对230颗脉冲星开展常规观测，以期为费米卫星（Fermi satellite）探测与表征γ射线脉冲星提供所需的精确脉冲星历表（ephemerides）。本项目的核心科学目标包括：扩充已知γ射线脉冲星的样本规模，覆盖射电亮脉冲星与射电静默脉冲星两类；获取高精度脉冲轮廓；并表征其相位分辨高能能谱。在射电观测波段，本次观测还将助力我们开展多项研究：发现脉冲星自转突变事件，表征计时噪声特性，探究色散与旋转量的变化规律，以及深化对单脉冲现象学的认知。截至目前，依托本合作项目与P574数据集已产出48篇学术论文，本团队成员均为其中部分论文的（共同）作者。该数据集已支撑波尔多研究团队与斯坦福大学的多名学生完成博士学位论文，且目前仍被广泛应用（详细说明见正文）。
