论文摘要
GRB 190114C的伽马射线爆发的多波大长度观察为研究GRB次要的发射机制打开了一个新窗口。它的高能（VHE; $ \ gtrsim 100 $ gev）检测激发了对排放的逆康普顿解释，但尚未进行测试。在这里，我们将余辉的早期排放从68秒重新审视，并使用kev进行TEV数据集进行建模似然分析。我们首次在合成模型上首次计算组合同步加速器（SYN）和同步加速器自compton（SSC）模型中的统计偏好。与较早的分析一致，在68到110秒之间可以找到对SSC模型的不稳定偏好，这也可以通过随附的仪器之间的系统跨校准效应来解释。我们得出的结论是，对这两个模型之一没有稳定的统计偏好。
Multiwavelength observation of the gamma-ray burst, GRB 190114C, opens a new window for studying the emission mechanism of GRB afterglows. Its Very-High-Energy (VHE; $\gtrsim 100$ GeV) detection has motivated an inverse Compton interpretation for the emission, but this has not been tested. Here, we revisit the early afterglow emission from 68 to 180 seconds and perform the modeling likelihood analysis with the keV to TeV datasets. We compute for the first time the statistical preference in the combined synchrotron (syn) and synchrotron self-Compton (SSC) model over the syn-only model. In agreement with earlier analyses, between 68 and 110 seconds an unstable preference for the SSC model can be found, which can also be explained by systematic cross calibration effect between the included instruments. We conclude that there is no stable statistical preference for one of the two models.
