Fermi LAT盲搜索发现Gamma-ray脉冲星

Fermi LAT Discovery of Gamma-ray Pulsars in a Blind Search

P. M. Saz Parkinson, M. Dormody, M. Ziegler

摘要:

费米伽马射线太空望远镜(前GLAST)上的大面积望远镜(LAT)相对于上一代伽马射线望远镜具有更高的灵敏度,显着增加了天空中已知伽马射线源的数量,包括伽马星。除了搜寻已知射电望远镜的伽马射线辐射外,现在还可以仅根据伽马射线数据成功地对射电望远镜进行盲搜索,目的是发现新的潜在无线电静默(类盖明加)射电望远镜。我们描述了我们的方法和一些最近的结果,从我们的搜索,使用时间差分技术,这导致了大量新的伽马射线天体的发现。

英文摘要:

The Large Area Telescope (LAT) on the Fermi Gamma-ray Space Telescope (formerly GLAST), with its improved sensitivity relative to previous generation gamma-ray telescopes, is significantly increasing the number of known gamma-ray sources in the sky, including pulsars. In addition to searching for gamma-ray emission from known radio pulsars, it is now possible to successfully perform blind searches for pulsars on the gamma-ray data alone, with the goal of uncovering a new population of potentially radio-quiet (Geminga-like) pulsars. We describe our methods and some recent results from our searches, performed using the time-differencing technique, which have resulted in the discovery of a large number of new gamma-ray pulsars.
