Parkes observations for project P574 semester 2009OCTS

We request time to observe 160 pulsars on a regular basis in order to provide accurate ephemerides necessary for the detection of gamma-ray pulsars with the Fermi and AGILE satellites. 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, to characterise their high energy spectra and phase resolved spectroscopy of the brightest pulsars. 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 2 Agile papers, 4 Fermi papers, 3 radio papers and authors on 3 papers in submission. The data are contributing to the PhD theses of Lucas Guillemot and Damien Parent from the Bordeaux Fermi group.

本研究申请观测时长以定期开展160颗脉冲星（pulsars）的观测，从而获取精准的星历表（ephemerides），为利用费米（Fermi）卫星与AGILE卫星探测伽马射线脉冲星（gamma-ray pulsars）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数量，涵盖射电亮（radio loud）与射电宁静（radio quiet）两类；获取精准的脉冲轮廓（pulse profiles）；刻画其高能能谱，并对最明亮的脉冲星开展相位分辨光谱（phase resolved spectroscopy）研究。在射电波段的观测中，本团队还可借此发现脉冲星自转突变（glitches），刻画计时噪声（timing noise）特性，研究色散（dispersion）与旋转量（rotation measure）的变化规律，并加深对单脉冲现象学（single pulse phenomenology）的认知。截至目前，本团队已作为（共同）作者发表2篇AGILE相关论文、4篇费米相关论文、3篇射电波段研究论文，另有3篇论文处于投稿阶段。本次观测产生的数据正支撑来自波尔多费米研究组的Lucas Guillemot与Damien Parent完成其博士学位论文。
