标题： Spectrum and Morphology of the Very-High-Energy Source HAWC J2019+368

摘要： MGRO J2019+37区域是天空中在太赫兹能量下最明亮的源之一。它在两年的HAWC目录中被检测为2HWC J2019+367，在这里我们使用HAWC的数据对该区域进行了详细研究。此分析将该区域分解为两个源：HAWC J2019+368和HAWC J2016+371。我们将HAWC J2016+371与演化的超新星遗迹CTB 87相关联，尽管在此分析中的低显著性阻止了目前的详细研究。对HAWC J2019+368的形态（包括可能的能量依赖形态）和光谱的研究是本工作的重点。我们将HAWC J2019+368与PSR J2021+3651及其X射线脉冲星风星云，即蜻蜓星云相关联。对HAWC和Suzaku测量的光谱进行建模揭示了一个$\sim$7千年的脉冲星和星云系统，在X射线和${\gamma}$-射线能量下产生观测到的辐射。 显示英文摘要

摘要： The MGRO J2019+37 region is one of the brightest sources in the sky at TeV energies. It was detected in the 2 year HAWC catalog as 2HWC J2019+367 and here we present a detailed study of this region using data from HAWC. This analysis resolves the region into two sources: HAWC J2019+368 and HAWC J2016+371. We associate HAWC J2016+371 with the evolved supernova remnant CTB 87, although its low significance in this analysis prevents a detailed study at this time. An investigation of the morphology (including possible energy dependent morphology) and spectrum for HAWC J2019+368 is the focus of this work. We associate HAWC J2019+368 with PSR J2021+3651 and its X-ray pulsar wind nebula, the Dragonfly nebula. Modeling the spectrum measured by HAWC and Suzaku reveals a $\sim$7 kyr pulsar and nebula system producing the observed emission at X-ray and ${\gamma}$-ray energies.
