Gamma-ray脉冲星的费米Gamma-ray空间望远镜观测

Fermi Gamma-ray Space Telescope Observations of Gamma-ray Pulsars

P. M. Saz Parkinson

摘要:

最近发射的费米伽马射线空间望远镜(原GLAST)上的大面积望远镜具有大视场和有效面积,加上其出色的计时能力,有望使伽马射线天体物理学领域发生革命性变化。与EGRET相比,灵敏度的大幅提高预计将导致发现许多新的伽马射线脉冲星,这反过来又将导致我们对脉冲星物理学和银河系中中子星作用的理解取得根本性进展。几乎在发射后不久,费米就清楚地探测到了所有以前已知的伽马射线双星,并对这些双星产生了高精度的结果。正在对已知(主要是射电)脉冲星进行广泛的射电和X射线计时活动,以促进新伽马射线脉冲星的发现。此外,正在使用一种高效的时间差技术对无线电静默卫星进行盲目搜索,这已经导致了新的发现。我提出了一些最近的结果,从搜索进行费米数据,盲搜索,并使用同期的时间已知的无线电天文学家。

英文摘要:

The Large Area Telescope on the recently launched Fermi Gamma-ray Space Telescope (formerly GLAST), with its large field of view and effective area, combined with its excellent timing capabilities, is poised to revolutionize the field of gamma-ray astrophysics. The large improvement in sensitivity over EGRET is expected to result in the discovery of many new gamma-ray pulsars, which in turn should lead to fundamental advances in our understanding of pulsar physics and the role of neutron stars in the Galaxy. Almost immediately after launch, Fermi clearly detected all previously known gamma-ray pulsars and is producing high precision results on these. An extensive radio and X-ray timing campaign of known (primarily radio) pulsars is being carried out in order to facilitate the discovery of new gamma-ray pulsars. In addition, a highly efficient time-differencing technique is being used to conduct blind searches for radio-quiet pulsars, which has already resulted in new discoveries. I present some recent results from searches for pulsars carried out on Fermi data, both blind searches, and using contemporaneous timing of known radio pulsars.
