摘要:

自2008年8月12日以来,费米号上的伽马射线暴监测器(GBM)一直在为天文学界提供连续的数据。在本文中,我们提出了这些连续数据的头三年的分析结果,使用地球掩星技术监测目录的209个来源。从这个星表中,我们探测到99个源,包括40个低质量X射线双星/中子星系统,31个高质量X射线双星中子星系统,12个黑洞双星,12个活动星系,2个其他源,加上蟹状星云和太阳。在100-300 keV波段探测到了其中9个源,包括7个黑洞双星、活动星系Cen A和蟹状星云。在300-500 keV波段也探测到了蟹状星云X-1和天鹅座星云X-1。GBM为100 keV以下的其他天空监测器提供补充数据,是唯一一个100 keV以上的全天监测器。所有目录源的最新光变曲线可以在http://heastro.phys.lsu.edu/gbm/上找到。

英文摘要:

The Gamma ray Burst Monitor (GBM) on board Fermi has been providing continuous data to the astronomical community since 2008 August 12. In this paper we present the results of the analysis of the first three years of these continuous data using the Earth occultation technique to monitor a catalog of 209 sources. From this catalog, we detect 99 sources, including 40 low-mass X-ray binary/neutron star systems, 31 high-mass X-ray binary neutron star systems, 12 black hole binaries, 12 active galaxies, 2 other sources, plus the Crab Nebula, and the Sun. Nine of these sources are detected in the 100-300 keV band, including seven black-hole binaries, the active galaxy Cen A, and the Crab. The Crab and Cyg X-1 are also detected in the 300-500 keV band. GBM provides complementary data to other sky-monitors below 100 keV and is the only all-sky monitor above 100 keV. Up-to-date light curves for all of the catalog sources can be found at http://heastro.phys.lsu.edu/gbm/.
