BeppoSAX的伽马射线暴分类
Classification of BeppoSAX's Gamma-Ray Bursts
摘要：
BeppoSAX号卫星目录是最近出版的。在本文中，我们分析-使用极大似然（ML）的方法-持续时间的目录中列出的1003伽玛暴的持续时间分布。最大似然法可以区分长时程组和中时程组。仅在96%的显著性水平下识别短爆发群。MC模拟也已应用，并给出了类似的显着性水平; 95%。然而，在康普顿伽马射线天文台的观测之后，短暴的存在并不是一个科学问题。我们的次要结果是这一众所周知的事实，即在BeppoSAX号卫星的数据中，短脉冲没有得到充分的体现，这主要是由不同的触发系统造成的。我们的主要成果是确定了BeppoSAX数据中的中间组。因此，四颗不同的卫星（CGRO、Swift、RHESSI和BeppoSAX）观测到了中间型伽马射线暴。
英文摘要：
The BeppoSAX Catalog has been very recently published. In this paper we analyze - using the Maximum Likelihood (ML) method - the duration distribution of the 1003 GRBs listed in the catalog with duration. The ML method can identify the long and the intermediate duration groups. The short population of the bursts is identified only at a 96% significance level. MC simulation has been also applied and gives a similar significance level; 95%. However, the existence of the short bursts is not a scientific question after the Compton Gamma-Ray Observatory's observation. Our minor result is this well-known fact that in the BeppoSAX data the short bursts are underrepresented, mainly caused by the different triggering system. Our major result is the identification of the intermediate group in the BeppoSAX data. Therefore, four different satellites (CGRO, Swift, RHESSI and BeppoSAX) observed the intermediate type Gamma-Ray Burst.
