Parkes observations for project P675 semester 2010OCTS

The Fermi satellite has detected more than 600 unidentified gamma-ray sources. We know that many of these will be associated with the most energetic and fascinating radio pulsars. By selecting the gamma-ray pulsars showing pulsar-like properties we expect to discover tens of new millisecond and young, energetic pulsars. Compared to large survey projects this presents a huge return. These pulsars are of great interest for a range of different science. In particular, millisecond pulsars are excellent targets for precision timing, allowing for tests of gravitational theories, use in gravitational wave detectors and for studying binary formation. Since these pulsars are associated with gamma-ray emission, their study is particularly important as we have a very limited understanding of the emission mechanisms in gamma-ray pulsars, which can only be understood through further observations in radio and gamma-rays.

费米卫星已探测到600多个未识别的伽马射线源。我们已知其中许多源与最具能量且引人入胜的射电脉冲星相关联。通过筛选具有脉冲星特征的伽马射线脉冲星，我们有望发现数十颗新的毫秒脉冲星以及年轻的高能脉冲星。与大型巡天项目相比，这一方法的回报极为可观。这些脉冲星在多个科学领域具有重要研究价值。特别是，毫秒脉冲星是精密计时的理想目标，可用于引力理论检验、引力波探测器以及双星形成研究。由于这些脉冲星与伽马射线辐射相关，其研究尤为重要——我们对伽马射线脉冲星的辐射机制了解极为有限，唯有通过进一步的射电与伽马射线观测方可深入理解。
