对银河系内中子星系统的高能伽玛射线观测研究

本项目主要基于费米伽玛射线望远镜上搭载的大视场望远镜的观测数据，研究银河系内中子星系统的高能辐射。脉冲星是银河系内最可能的伽玛射线中子星系统，我们将搜索其中特殊的一类－强磁星在某些特定时段内的伽玛射线辐射，并利用搜索结果限制强磁星可能的辐射机制。我们还将在费米望远镜探测到但未知类型的低银纬源中搜索新的伽玛射线脉冲星，为研究脉冲星相关问题提供更多的样本。另外，脉冲星星风云和超新星遗迹也是银河系内重要的伽玛射线源，它们都是中子星相关天体，我们将搜索新的伽玛射线脉冲星星风云和超新星遗迹，并利用它们的宽波段能谱分布讨论其辐射模型。

This project will investigate the high energy emission of the neutron star systems in the Galaxy with observations of the large area telescope (LAT) onboard the Fermi gamma-ray space telescope. Pulsars are the most possible gamma-ray neutron star systems in the Galaxy. We will search gamma-ray emission from one particular type of pulsars - magnetars during some specific time periods, and with the LAT observations we will confine the possible high energy emission mechanism for magnetars. We will also search for new gamma-ray pulsars among low-latitude Fermi unassociated sources to provide more samples for the investigations related to pulsars. In addition, pulsar wind nebulae and supernova remnants are important gamma-ray sources in the Galaxy and all related to neutron stars, we will search for new gamma-ray pulsar wind nebulae and supernova remnants, and discuss their emission models with the broad-band spectral energy distributions.
