论文摘要
我们介绍了费米卫星上伽马射线爆发显示器（GBM）的第一个出色动机的背景模型。这种有力动机的背景模型有可能显着改善费米/GBM的科学产量，因为它可用于改善伽马射线爆发（GRB）和其他来源的光谱分析和定位的背景估计。此外，由于长度/弱或缓慢上升的瞬态事件不会激活现有的触发算法之一，因此它也可能导致检测新的瞬态事件。在本文中，我们显示了这种出于物理动机的背景模型的推导，其中包括不同背景源的建模以及对GBM响应的正确处理。虽然本文的目的是介绍该模型，而不是开发瞬态搜索算法，但我们证明了该模型通过显示四个申请，即（1）对于超长的GRB 091024，（2）符合GBM看到的背景的能力，即V404 Cygni Cygni cygni cygni cygni cygni cygni cygni grb，（2）在2015年6月9日（3）。
We present the first physically motivated background model for the Gamma-Ray Burst Monitor (GBM) onboard the Fermi satellite. Such a physically motivated background model has the potential to significantly improve the scientific output of Fermi/GBM, as it can be used to improve the background estimate for spectral analysis and localization of Gamma-Ray Bursts (GRBs) and other sources. Additionally, it can also lead to detections of new transient events, since long/weak or slowly rising ones do not activate one of the existing trigger algorithms. In this paper we show the derivation of such a physically motivated background model, which includes the modeling of the different background sources and the correct handling of the response of GBM. While the goal of the paper is to introduce the model rather than developing a transient search algorithm, we demonstrate the ability of the model to fit the background seen by GBM by showing four applications, namely (1) for a canonical GRB, (2) for the ultra-long GRB 091024, (3) for the V404 Cygni outburst in June 2015, and (4) the ultra-long GRB 130925A.
