摘要

对伽马射线暴(GRB)喷流的研究主要集中在光谱能量分布(SED)的伽马射线部分,以了解喷流的特性及其物理学原理。最近的理论发展转向了 SED 的低能量部分,以测试相互竞争的喷流模型。我们考虑应用宽视场 X 射线探测器来扩大 SED 的观测范围,并更好地区分光谱模型,目的是解决费米和雨燕等飞行任务灵敏度或低于灵敏度时存在的理论特征。介绍了拟议的小卫星参考任务,并对模拟的 GRB 进行了分析,以确定与费米-伽马射线暴监测器(GBM)相比,小卫星在理解 SED 方面的改进。利用 GRB 群体模型模拟参考任务的探测率,并与解析模型所需的能量通量相联系,以找到参考任务能比 Fermi-GBM 更好地解析 GRB 的估计率。我们将讨论这些方法和结果以及这类任务的科学背景。

Gamma-ray burst studies with wide-field X-ray detectors on a SmallSat platform
The study of gamma-ray burst (GRB) jets has focused predominantly on the gamma-ray portion of the spectral energy distribution (SED) to understand jet properties and their physics. Recent theoretical development has turned to the lower-energy side of the SED to test competing jet models. We considered the application of wide-field X-ray detectors to extend the observation of the SED and for better distinguishing spectral models, aimed at resolving theoretical features existing at or below the sensitivity of missions such as Fermi and Swift. A proposed SmallSat reference mission is introduced, and analysis is conducted on simulated GRBs to determine its improvement in understanding the SED compared with the Fermi-gamma-ray burst monitor (GBM). Detection rates of the reference mission are simulated using a GRB population model and convolved with the energy flux needed to resolve models to find estimated rates of GRBs that the reference mission can resolve better than Fermi-GBM. We discuss the methods and results along with the scientific context for this type of mission.
